Gas is a kind of unconventional natural gas (mainly composed of methane) stored in coal seam. It is a harmful gas emitted automatically during the process of coal mining. Among the accidents in China's coal mines, there is a high value of utilization, so it is called "second coal resources".
The development and utilization of gas and gas can protect the global environment, improve the safety of coal mines and increase the multiple functions of new energy. In order to make rational use of gas and change the damage, the gas engine is integrated into a generating set, which not only solves the problem of exhaust air pollution to the atmosphere, but also reclaims the green energy of gas.
The use of gas and gas to generate electricity is an economical and effective way to turn waste into treasure. Besides, China has abundant CBM resources, and its gas resource volume is about 35 trillion cubic meters, which is similar to that of natural gas resources (about 38 trillion cubic meters), and has great market prospect.
1) the gas station should be close to the gas pumping station, gas storage tank or mine substation (Institute), and conforms to the state "coal mine safety regulations" and the relevant regulations.
2) the site location should have good natural ventilation condition.
3) the overhead communication lines and the overhead power lines are not allowed to cross the gas power station.
4) the site should be located by flood, waterlogging and tide threatened areas, should avoid the dam or dike breach may be flooded area. When unavoidable, it is necessary to have reliable measures for flood control and drainage.
5) 站址选择应避开下列地段和地区： a、地震活动断层带和设防烈度高于9度的地震区； b、有滚石、泥石流、滑坡、流沙、冲沟、溶洞等地段； c、采动塌陷未稳定区； 低浓度瓦斯发电机组主要技术要求
5) site selection should avoid the following areas and regions: A, seismic active fault zone and seismic fortification intensity is higher than the 9 degree; B, the rolling stones, debris flow, landslide, sand, gullies, caves and other areas; C, collapse is not stable mining zone; the main technical requirements of low concentration gas turbine
