Abstract: The present invention relates to a method for sorting and utilizing coal and rock for a coal and rock combined mining face, and is especially applicable to the sorting and utilization of coal and rock mined from a coal and rock combined mining face when an extremely thin coal seam is used as a protective layer in combined mining of multiple coal seams.

Abstract: A method of performing coupled drilling, flushing, and slotting operations on a coal seam, which has a high gas content and prone to bursts, is described herein. The method is aimed to relieve pressure and increase permeability when drilling a through-seam borehole to pre-drain gas belts in a coal mine roadway. The pressure relief and permeation method of the present invention adjusts the water jet water inlet pressure in different stages according to the different positions of the drilling construction, and controls the water during drilling. At drilling stage, the jets are respectively subjected to low-pressure water flow drilling and medium-pressure water flow flushing. When withdraw drilling, the high-pressure water flow slotting is carried out. By doing so, the pressure is relieved in a low, medium, high stepwise manner.

Abstract: The present invention relates to a “drilling-flushing-slotting” coupled pressure relief and permeability increasing method for a high gas outburst coal seam, which is more particularly suitable for the pressure relief and permeability increasing when gas of a roadway band of the high gas outburst coal seam is pre-extracted through crossing boreholes. On the basis of the crossing borehole pre-extraction measures for the coal seam gas, the hydraulic flushing and the hydraulic slotting are reasonably combined, and a “drilling-flushing-slotting” dedicated device is utilized to implement the coupled operation of “low pressure drilling-medium pressure flushing-high pressure slotting” in a borehole, so that the coal in the pre-extraction area is deformed and moved to form network cracks, passages are provided to the desorption flow of the gas, and the gas is easier to extract.
