摘要
煤矿松软岩层巷道具有锚固效果差,变形严重等特点,严重影响整体结构的稳定性。以松软岩层为研究对象,以下霍矿松软岩层硐室为试验点,对其采用喷锚注支护设计,通过现场矿压监测,检验了锚注支护的效果,达到了预期效果。
With characteristics of poor anchoring effect and serious deformation, the soft rock tunnel of coal mine has affect the stability of the whole structure seriously. Taken the soft rock of the chamber of Xiahuo Coal Mine as the test point, spray bolting and grouting support design was done. Through site mine pressure monitoring, application effects of bolt-grouting support was tested and expectation effects reached.
