1results about How to "Potential" patented technology

This invention belongs to the field of underground coal mine drilling technology, specifically a method for integrated directional drilling layout that combines pressure relief, extraction, and monitoring. It includes: excavating a drilling site near the coal seam in the main roadway of the mining area; and constructing boreholes in the coal seam, the lower part of the caving zone, and the fracture zone in a single operation within the drilling site before the working face roadway excavation. The coal seam boreholes are used to detect the height of the coal seam roof and floor, gas extraction, pressure relief, and monitor drill cuttings volume during roadway excavation and mining; gas extraction is performed via a connection to the extraction pipeline. The lower part of the caving zone boreholes are used for pre-extraction of gas from the coal seam, gas extraction from the goaf after working face mining, and determining the position of the coal seam roof; gas extraction is performed via the extraction pipeline. The fracture zone boreholes are used for gas extraction from the fracture zone after working face mining, with the gas incorporated into the extraction pipeline. This invention pre-depressurizes the coal seam, extends the drilling extraction cycle, monitors the position of the coal seam roof and floor, and maximizes borehole utilization.
