Problems solved by technology
At present, the single drainage method adopted for gas control is deeply affected by underground temperature and gas concentration, the extraction environment is harsh, and the mismatch between the operating parameters of the drainage system and the variable mine gas parameters seriously affects the gas control effect, making the gas resources impossible. This problem is particularly prominent in the process of deep gas control

The invention relates to a gas control, extraction and utilization integrated deep coal resource development method, and belongs to the technical field of gas development and utilization. The gas control, extraction and utilization integrated deep coal resource development method comprises the following steps: arranging two bottom extraction roadways and two coal roadways; pre-extracting gas by using the bottom extraction roadway seam-crossing hole drilling, coal roadway parallel hole drilling along seams and hydraulic cave building mode; and arranging a high extraction roadway in an interioralternate airway so as to extract gas in a goaf. According to the gas control, extraction and utilization integrated deep coal resource development method, an anti-explosive electric control valve isarranged at an air return extraction main pipeline; gas parameters of a main extraction roadway are monitored through a sensor module; different extraction parameters are adopted for a pump set according to variations of the gas extraction concentration; the output end of the extraction pump set is connected with a gas power generation device and a power distribution device; and the rear end of the power distribution device is connected with a refrigerator and a grid combination line. When the bottom-hole heat damage is controlled by utilizing the refrigeration effect of the refrigerator, gasresources are utilized properly, abundant electric power is generated, the economic benefit is improved, and the purpose of gas resource control, extraction and utilization integration is fulfilled.
Description
technical field [0001] The invention belongs to the technical field of gas development and utilization, and in particular relates to a method for developing deep coal resources integrating gas control, extraction and utilization. Background technique [0002] With the continuous increase of mining depth and mining intensity, the natural conditions of mining areas, gas geological conditions and coal mining technology have undergone significant changes. Deep mining complicates the factors affecting the occurrence of gas disasters, and gas disasters tend to be coupled with other disasters. The rise of deep gas pressure and content undoubtedly intensifies the possibility of coal and gas outburst, and even interweaves mining conditions such as high ground stress, high outburst risk, and low gas permeability. Deep coal resources are faced with problems such as high rock pressure, high ground temperature, coal and gas outbursts, and aggravated spontaneous combustion of coal seams,...
