以王坡煤矿3204工作面沿空侧巷道为研究对象,采用FLAC2D研究3204工作面沿空侧多条巷道在掘进期间分别采用锚网支护和锚网支护+注浆锚索补强支护的情况下,巷道表面的位移、应力和塑性区变化规律。研究结果表明:相邻巷道掘进时产生的动压会对已掘巷道的稳定性造成影响,采用锚网支护+注浆锚索补强支护后增加了巷道的抗变形能力,为回采过程中巷道稳定提供了保证。 Taking the 3204 working face of Wangpo Mine along the side of aisle as the research object, FLAC2D study 3204 working face along the airside side of the roadway during the excavation were used anchor net support and anchor net support + grouting anchor cable reinforcement support Of the case, the laneway surface displacement, stress and plastic zone changes. The results show that the dynamic pressure generated during the excavation of adjacent roadway will affect the stability of the roadway that has been excavated, and the deformation resistance of the roadway increases with the support of bolting wire mesh and grouting anchor cable Roadway stability provided a guarantee.
