Steps, 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.
2 Power-saving measures 1 Relying on scientific and technological progress, increasing the investment in equipment technology reform, and promoting the high-energy-consumption equipment transformation group, the raw coal production and electricity consumption accounts for about 7 times of the enterprise's electricity consumption. Therefore, do a good job in the technical transformation of large-scale operation equipment. At the same time, in order to solve the problem of capital difficulties in various mines, the group company set up a special fund for equipment energy-saving technology reform loans, supported the technical reform of various mine equipment, and determined the technical reform procedures for testing, research and demonstration of lending. For example, the West Gate Well 70822 of Hanqiao Coal Mine passed the counterpart design and transformation technology of Shenyang Aerospace Research Institute. The efficiency was increased from 5 micron to 71. Yang, and the annual power saving was 342,800 1 Jia. The investment was recovered in 8 months. The central fan of 12501 in Qishan Coal Mine adopts the series of speed regulation technology of Shanghai Coal Research Institute. The annual energy saving of 10,000 yuan is 438,500 yuan. Since 1997, the accumulated investment has been nearly 3 million yuan, and 39 sets of equipment have been upgraded and rebuilt. 10 sets of wind turbines for design and transformation and series speed regulation; 16 sets of main drainage pumps for mines; 5 sets of mine hoist winches; 5 new sets of pressure fans, saving 4.8 million annual savings of 1.92 million yuan The requirements for separation of service lines, first of all, improve the electricity metering work, and vertically calculate the total amount of electricity on all ground units and electricity assessment points. According to statistics, all units have installed 1 208± of electric energy, and 5,206 households in the village. Strengthening the analysis of electricity consumption and assessing the industrialization through electricity analysis to check the problems and reasons for the completion of the power consumption plan of the unit, to find out the various electricity consumption rules and development trends, in order to improve the level of electricity management, improve work at the same time, Power analysis also provides a strong basis for the development of post-electricity plans and priorities.
3 Yaxing's effective energy-saving measures, all-round consumption reduction is the pressure of the wind turbine timing centralized supply group mining and the winch bottom loading and loading are all driven by pressure.
The main air pressure fan on the ground needs 24 long-term operation, which consumes a large amount of electric energy. For this reason, the upper and lower port loading pneumatic system of the winch well is transformed into an electric system; the downhole operation cycle is improved, and the centralized centralized air supply is implemented. At present, the company's various mine pressure fans Running time is 241!
1 Lowering a 83-well well-twisted timed 1 person is to change the production cycle of the production class, concentrate on two shifts of production class renovation, and implement centralized underground transportation to implement centralized power supply through the implementation of energy-saving measures. Significant decline, in 2001, smashing, mentioning, screaming that compared with last year's first phase, the reduction of 5.02 million pressure blower electricity is lower than the last year's call for 2.4 million underground.
According to statistics, through the implementation of the above-mentioned energy-saving measures, the annual electricity saving 3200 saves electricity costs of 12.8 million yuan. At the same time, it is clear that saving electricity is a long-term benefit project, which is the need of coal mine development, and also under market economy conditions. The inevitable choice to promote the virtuous circle of the enterprise, in addition to the assistant engineer of the power supply department of the State Mining Group Co., Ltd.
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. product.
2 Improve measurement methods, strengthen the use of electricity analysis and assessment management
Gantry Flame Cutting Machine is the most widely used metal plate CNC Cutting Machine at the present stage.
