Study on Key Parameters of Directional Long Borehole Layout in High-Gas Working Face
This research aims to obtain a new way based on the directional long borehole layout to investigate the gas migration behavior of coal bed methane. In view of the study of the oil-type gas reservoir and the influence range of mining on the working face in the surrounding rock, the paper puts forward...

| description | This research aims to obtain a new way based on the directional long borehole layout to investigate the gas migration behavior of coal bed methane. In view of the study of the oil-type gas reservoir and the influence range of mining on the working face in the surrounding rock, the paper puts forward the optimization method of the directional long borehole layout of the surrounding rock and the method of the borehole layout with comprehensive consideration of the influence of mining on the failure of the roof and floor and the distribution of surrounding rock gas-bearing reservoirs. The test results showed that the layout horizon of the directional long boreholes is determined, and the layout was within the height range of 20–40 meters, clarified the relationship between the drainage data and the exposure level of the borehole and the layout of the borehole, compared the gas concentration in the upper corner of the working face before and after the drainage, and constructed a three-dimensional comprehensive drainage mode for the high-gassy working face, which provided a worth-promoting method that supports surrounding rock oil-type gas and gas treatment in the high-gas mining area. |
