深埋软岩巷道围岩控制技术研究

Study on Durrounding Rock Control Technology of Deep Buried Soft Rock Roadway

针对深埋软岩巷道围岩变形严重问题,以山西某矿1307工作面皮带巷地质条件为基础,通过分析巷道围岩应力、结构、力学特性等,确定了该巷道围岩变形机理,针对性对巷道支护方案进行了优化,并加以喷浆来控制巷道围岩表面变形。现场实践表明,该方案能有效控制围岩变形,有利于巷道围岩稳定。

In view of the serious deformation of surrounding rock in deep buried soft rock roadway, taking the geological conditions of belt roadway in 1307 working face of a mine in Shanxi Province as an example, by analyzing the stress, structure and mechanical properties of surrounding rock of the roadway, the deformation mechanism of surrounding rock of the roadway is determined, the roadway support scheme is optimized, and the Shotcreting is used to control the deformation of surrounding rock surface of the roadway. Field practice shows that this scheme not only effectively controls the deformation of surrounding rock, but also is conducive to the stability of roadway surrounding rock.
