Technology system of hydraulic disturbance gas drainage in underground mine

Based on the deep first mining seam with the outbourst danger and the high eficient gas drainage from a single ow permeabilty and outburst seam as afoothoid under the condtton of the mining without a protective layer and based on the problems existed in thegas drainageof the underground mine a hydraulic disturbance gas drainage technology in the underground mine was introduced and defned.Based on a fine geologicaldesign optimization. ling pressire an fushing repair dsturoance emhanced and gas crainage evaluation quanttative as the technical main line ,a hyraulc disturbance gas drainage technology system of the underground mine was provided. The paper stressed the 1 iten key technologies and the functionfeatures and ite appication condtions of th equioment.Acoding othe problensof the techncal system existed in the basic theory,prssure relesed and permeablityimprovement key flechnology and th matched equipmentthe paper hed tat thenalysis on fine gas drainage geologystudying on the basic theory of the coal and gas co-mining mode in a single lowpermeability seanm,theimprovement and inegraton of the pressure released and pemeablit key fechnology and the seres and ineli ent ofthe matched equipment oud be key study point in thelate technical s stem improvement.
