Increase investment in technological transformation, accelerate the transformation of high-energy-consuming equipment and strengthen the implementation of power-saving measures. This is the only way for manpower to save money, reduce consumption and save money, and it is also the focus of future work.

1 The potential of coal mine power saving There are many unreasonable power consumption in the coal mine production process. This is also the incomplete statistics of coal mine energy conservation. The group company has two aspects in terms of power consumption. The electric energy is converted into photothermal energy through the electric light source and the electric furnace, which accounts for about the electricity used by the enterprise; the other is that the electric energy is converted into mechanical energy by the electric motor, which accounts for about 89% of the electricity used by the enterprise. According to statistical analysis, the electromechanical equipment currently used by the group company And lighting appliances are mostly poor performance. Compared with similar energy-saving new products, the pump efficiency is low. 1 Fans with low efficiency and double 7.5 1 or more are eliminated. Series product power supply system main transformer 7, above is a high-energy transformer lighting fixture 40 to 1 is a bright light. Most of the mouthlights are still inductive ballasts and energy-consuming fluorescent tubes. In addition, from the point of view of the group's power-saving management, there is no plan to use electricity without planning. The phenomenon of running water is not uncommon due to management differences. The electricity consumption per ton of coal varies greatly. From the above analysis, the power saving potential of the group company is very large.

17 New single-unit hydraulic props coal mining face supporting equipment is an indispensable equipment for coal mines. Due to various reasons such as geological conditions and equipment costs, most of the coal mining is used in China except for the coal mining face of some coal mines. The work surface support uses a single support device. The fully mechanized mining face is large in quantity and wide in scope. The new type of work surface single-support product developed by China University of Mining and Technology is a patented technology for two patent protections of national inventions and utility models.
