摘　　要：为解决在深井复杂地质条件下综采工作面开采过程中，由地应力引发的瓦斯突出和冲击地压问题，采用底板巷道抽排、回风巷本煤层注水、回风巷和采面深孔松动爆破卸压进行采面深孔卸压抽排，同时在采面增加了煤壁静压水措施，并分析了深部采动压力三带分布规律。试验结果表明，煤层瓦斯压力由2．4MPa下降到0．3～0．5MPa，卸压带不断加大，突出危险性明显降低。In order to solve the gas outburst and bumping problems occurred by the earth stress during the fully mechanized coal mining process under the deep mine complicated geological conditions, the gateway floor gas drainage, water injection in seam of the air retum gateway, vibration deep borehole blasting in the seam of the air return gateway and coal mining face wall for the strata pressure releasing, deep borehole gas drainage in the coal mining face wall for the starat pressure releasing and static pressure water injection in the coal wall of the coal mining face were conducted. The paper analyzed the mining pressure three zone distribution law in the deep mine. The test results showed that the seam gas pressure was reduced from 2.4 MPa to 0. 3 -0.5 MPa. The pressure released zone was continuously enlarged and the dangers of the gas outburst obviously reduced.
