【摘要】 针对某矿专用回风巷在掘进过程中接近三维地震勘探划定的陷落柱区域,采用反射共偏移探测技术在胶带巷进行了侧向探测,确定了探测范围内的专用回风巷掘进不会受到该陷落柱的影响,但会受到破碎带和煤厚变化的影响。实际揭露情况证实了探测结论,表明该技术对于指导巷道安全掘进具有实用价值。更多还原

【Abstract】 In order to further detecting collapse column explored by 3-d seismic exploration in driving roadway,applying reflection common-offset technology,it was believed that air-return roadway driving would not be influenced by this collapse column,but be influenced by broken zone and coal-seam thickness variation zone. Actual driving proved this conclusion,which showed this technology had practical value for referring roadway’s safe driving.更多还原
