软岩巷道的维护问题一直困扰着地下岩土工程界,已经成为阻碍煤矿安全生产的一个重要因素。为了进一步认清软岩巷道的控制机理及提出合理的控制思路,以某矿典型的软岩巷道为研究对象,在分析巷道围岩变形特征和现场观测围岩内部破裂规律的基础上,提出采用高强度锚网索组合控制巷道的思路,经过现场工业性试验,该方案可以有效地控制围岩的变形和内部裂隙发育,实现该类巷道围岩的稳定。
The maintenance of soft rock roadway has plagued the underground geotechnical engineering and has become an important factor that hinders the safe production of coal mines. In order to further understand the control mechanism of soft rock roadway and put forward reasonable control ideas, taking the typical soft rock roadway of a mine as the research object, based on the analysis of the deformation characteristics of the surrounding rock and the observation of the internal rupture law in the surrounding rock, High strength anchor net combination roadway control ideas, after field industrial test, the program can effectively control the deformation of surrounding rock and internal fissures development, to achieve the stability of such roadway surrounding rock.
