摘要
为解决恒源煤矿深部架空乘人车硐室断面大、构造复杂、含水多等因素带来的支护难题,基于圆形巷道塑性区理论,分析架空乘人车直墙半圆拱形巷道围岩控制的关键,采用锚网索支护技术,并总结了施工过程中支护的关键技术要点。结果表明:在锚网索联合支护下,硐室围岩变形得到了有效控制。
In order to solve support difficulties induced by mine deep manned aerial cableway chamber＇s large section, complicated structure and highest water content, based on round roadway plastic zone theory, analyzing the key of manned aerial cableway stalk semi-circle arch roadway surrounding rock control, cable anchor supporting technology was conducted and concluded the key of construction support. It showed that chamber surrounding rock deformation got control effectively under the cable anchor combination support.
