煤矿顺槽掘进施工与变形量监测分析

Analysis of Tunneling Construction and Deformation Measurement in Coal Mine

以青瓷窑煤矿5602回风顺槽掘进施工为工程背景,对顶板采用锚杆、金属网和锚索联合支护,帮部采用螺纹钢锚杆和金属网联合支护的方式提高顺槽工作面稳定性。为验证支护效果,布置测点进行变形量监测,分析监测结果说明支护结构可有效保证顺槽结构稳定。

Taking the construction of the 5602 return air trench in Qingciyao Coal Mine as the engineering background,the roof is supported by bolt,metal mesh and anchor cable,and the side is supported by rebar bolt and metal mesh to improve the stability of the working face.In order to verify the support effect,the deformation monitoring is carried out at the measuring points,and the analysis and measurement results show that the support structure can effectively ensure the stability of the channel structure.
