摘　　要：以石炭系疏松煤层大断面掘进巷道过大断层支护为例,对疏松煤层大断面掘进支护技术进行了探讨,通过物探结合钻探探测出断层的参数。经科学计算,精准掌握大断面巷道的围岩松动圈范围,再及时采用加强支护结合煤层注浆的综合支护技术方案,安全快速地通过了断层区。该方案对其他相同地质条件的煤矿具有极高的借鉴意义。Taking the large cross-section driving in loose coal seam of Carboniferous System as an example,this paper discussed the technology of large cross-section driving in loose coal seam.Through geophysical exploration and drilling,it detected the parameters of the fault,accurately grasped the scope of surrounding rock loose circle of large cross-section driving after scientific calculation,and then timely adopted the comprehensive support technology scheme of strong support and coal seamgrouting to pass through the fault area safely and quickly.The scheme is of great significance to other coal mines with the same geological conditions.
