Pingmei Group successfully used large-diameter tube wells to extract gas power generation technology. It is understood that this technology is advanced at home and abroad, and its successful application has filled the gap in the ground-discharge gas power generation technology of coal system in Henan Province.
The technology mainly drills vertically from the ground directly into the well, then enters the casing to form a tube well, and is connected to the underground gas drainage system, and uses the tube well to directly discharge gas from the ground. At the same time, a gas power station was built next to the ground gas pumping station, and the gas extracted from the pipe well was used to generate electricity. After the application of this technology, the gas concentration of the coal mining face is effectively reduced. At the same time, a sufficient gas source is provided for the gas power station, and the comprehensive utilization rate of gas is over 90%, which greatly reduces environmental pollution and realizes the comprehensive gas generation. use.
Up to now, the gas drainage pipe well has accumulated 1,106,200 cubic meters of gas and 864,600 kWh of gas.
