摘要
石炭井二矿21053工作面煤层倾角大，上部为上区段采空区，通过数值模拟分析，研究倾斜煤层中沿空掘巷矿压显现规律，通过对表面位移、围岩深部位移和锚杆（索）受力进行现场监测，探索在倾斜煤层沿空掘巷中应用锚网索支护技术。实践表明：倾斜煤层沿空掘巷采用锚网索支护技术是经济可行的。
On the base of 21053 mining face in the second colliery of Shitanjin,the application of bolt-mesh-cable support technology in steeply gob-side entry excavating laneway was explored. By the monitored data of surface and deep displacement of surrounding rock and bolt/cable pressure, the ground pressure behavior regularity and cable pressure identity of excavating laneway were obtained. The experiment showed that bolt-mesh-cable support system could be applied in the steeply gob-side entry excavating laneway.
