This article tells you how to choose Distribution Coal Mine Transformer for energy-efficient coal mine. help you to carry out mine construction and select a suitable mine Distribution Coal Mine Transformer .
Combined with the current development of society, there is the problem of high energy consumption and low energy utilization efficiency, which restricts the efficient development of social economy. The coal mining industry as a provider of energy consumption in energy consumption is also large, in the case of large energy cost investment, restricting the healthy development of coal mining enterprises, coal mining enterprises need to actively focus on the construction of energy-efficient mines, under the effective energy saving and emission reduction work to reduce the expenditure of energy costs.
Combined with the current problems of energy saving and emission reduction in coal mines, there are problems in coal mine production technology is not high, high energy consumption and rough management mode, so it is necessary to study the energy-saving measures of energy-saving mine construction.
As more and more coal mining enterprises attach importance to sustainable development, under the influence of the concept of low-carbon production, the construction of energy-saving mines has received the attention of many coal mining enterprises. At present, there are still certain problems in the emission reduction of energy-saving mines, specifically in the following aspects.
First, the rough and loose characteristics of the management mode. Specifically, some coal mining enterprises have not effectively completed the transition and transition from the planned economic system to the socialist market economy system, so they are not able to effectively do a good job of saving resources under the crude management mode.
Second, the technical level of coal mine production is not high. Some coal mining enterprises do not pay attention to the optimization of production technology and equipment, will cause greater energy loss because of equipment and technical problems, while the traditional equipment and technology can also exist a safety hazard, restricting the safe production of coal mines.
Third, the management level of coal mine production is relatively backward. In the lack of awareness of energy saving and emission reduction, many management work only pays attention to the benefits of coal mine production, and does not pay attention to the impact of coal mine production on the environment and the loss of resources, so many management work can not play a proper energy-saving effect .
Combined with the continuous development of the information age, which promotes the optimization and application of energy-saving equipment and energy-saving processes, combined with the need for coal mining enterprises in the construction of energy-saving mines, in order to better implement the requirements of energy-saving and sustainable development strategies, it is necessary to actively improve the scientific research investment in mining technology and equipment, so as to reduce energy loss through new equipment and new technologies. For example, green production technologies such as ore filling and ore-for-coal can be used to reduce the pollution of ore.
In addition, coal mining enterprises need to strengthen the training and recruitment of corresponding professional talents, so that they can more effectively play the application effect of energy-saving equipment and technology.
At the same time, the talents can also propose more effective energy-saving measures under the actual production of the mine to meet the construction needs of energy-saving mines .
Specifically on the loss of electrical energy, it is necessary to focus on the laying length of the cable, but also to emphasize the loss of electrical energy in terms of current strength, line resistance, etc. Specifically, the following aspects need to be done.
First, the power supply line should be reasonably designed to reduce the energy loss under the length of the power supply line.
Second, do a good job of line maintenance and inspection to avoid short circuits and other unexpected conditions.
Third, to actively choose reasonable wire materials to reduce the resistance of the circuit, maximize the efficiency of the power supply, the implementation of energy-saving mine construction needs.
The comprehensive utilization of coal mines can play an energy-saving effect, for example, when carrying out gas extraction operations, the mine construction can be carried out simultaneously, which can reduce the loss of resources.
In addition, in the normal production of the mine, active attention needs to be paid to the layout of the environment around the mine and other influencing factors to minimize the probability of gas explosion and improve the utilization rate of gas.
For the construction of energy-saving mines, it is necessary not only to reduce the consumption of electrical energy, but also to emphasize the comprehensive use of other coal mine energy sources in order to better accomplish the construction goals of energy-saving mines.
In the construction of energy-efficient mines, the overall consumption of electrical energy needs to be reduced so as to implement the strategic requirements of energy conservation and emission reduction.
First, the energy consumption of refrigeration in the summer mining process of a coal mining enterprise occupies about 25% of the overall energy consumption, so it is necessary to actively control the energy consumption of refrigeration to meet the construction needs of an energy-saving mine. Generally, you can choose a centralized, large-scale refrigeration system with frequency conversion to reduce the energy consumption of electrical energy by centralized refrigeration.
Second, in the winter coal mining, in the provision of heating and hot water services can be achieved through solar centralized systems or solar water heaters, but also in the heating mode through centralized heating by central air conditioning, reducing the loss of electrical energy.
Third, in the coal mine production needs to reduce the loss of electrical energy through the reasonable choice of lighting fixtures. In general, LED lights are actively used in plant lights, high pole lights and street lights to reduce power loss and meet the needs of building energy-saving mines.
In the mine production of coal mining enterprises, the demand for electrical energy is very large, among which, the Distribution Coal Mine Transformer is the main power supply equipment in coal mining enterprises, and its consumption of electrical energy resources can account for 6% of the total energy consumption, which is a large waste of electrical energy for the mine production. Therefore, under the energy-saving mine construction, it is necessary to improve the efficiency and reduce the loss of voltage.
When selecting an energy-saving Distribution Coal Mine Transformer , the mine should choose a new material and technology-based voltage Coal Mine Transformer , such as an amorphous alloy core Distribution Coal Mine Transformer , which has a good energy-saving effect.
In addition, in order to meet the needs of energy-saving construction in mines, the number and capacity of Distribution Coal Mine Transformer should be reasonably designed, and the automatic control of power supply should be paid attention to in the actual power supply, so as to improve the energy-saving effect.
For the construction of energy-saving mines in coal mining enterprises, in order to effectively implement the national strategy of sustainable development and energy saving and emission reduction strategy, coal mining enterprises need not only to reduce energy consumption through coal mining technology and construction management, but also to strengthen the use of green energy. For example, wind energy, solar energy and other renewable energy sources in nature can be reasonably applied with the actual situation, which can reduce the loss of fuel energy and electrical energy, as well as reduce the cost of coal mining enterprises in terms of energy expenditure, so that the construction of an energy-saving mine can be effectively completed.
In order to improve the energy saving effect in mine production, coal mining enterprises need to realize the energy-saving mine construction through the following aspects.
First, it is necessary to combine the actual situation of the mine in coal mining. Specifically to be combined with the coal seam distance in coal mining on the impact of mining, to be in the coal mining design phase for the coal seam thickness of the mining plan, so as to achieve effective energy-saving production after the operational process in the tunnel.
Second, the actual mining needs to be combined with the surrounding environment, the need to understand the terrain conditions, hydrological conditions and geological conditions around the mining, complex conditions will restrict the quality and efficiency of mining, in the absence of corresponding strategies to develop, will be different degrees of waste of human resources, fuel resources and time costs, etc., is not conducive to meeting the construction requirements of energy-efficient mines.
Third, the management in construction should be strengthened. Through effective management to reduce the risk of equipment failure, human operation and other aspects, so as to improve the efficiency and quality of mining under the implementation of the strategic requirements of energy saving and emission reduction.
At present, coal mining enterprises are more concerned about the construction of energy-saving mines in production, combined with the current problems in the construction of energy-saving mines in various coal mining enterprises, it is necessary to improve the energy-saving effect of mines through certain measures, specifically to improve the energy-saving awareness of coal mining enterprise managers and front-line employees, and then actively improve the mining technology and equipment investment in scientific research and strengthen the comprehensive utilization of coal mines.
Finally, it is also necessary to control the overall energy consumption of the power supply system and optimize the design of the production stage, so as to improve the energy utilization efficiency of the mine and reduce energy losses, and to promote the healthy development of coal mining enterprises under the effective implementation of energy-saving and emission reduction strategies.
