【摘要】 通过对巷道破坏及突水机理分析研究,确定在巷道突水地区采用浅部围岩注浆改性加固提高围岩强度和深孔高压注浆封水相结合的注浆方式,能有效控制围岩变形破坏,实现堵水目的,并取得较好的技术经济效果,已在突水巷道实施应用。更多还原

【Abstract】 The roadway destruction and the water bursting mechanism have been analyzed. A combination method of grouting reinforcement at the shallow surrounding rock area for strengthening the surrounding rocks and the deephole highpressure watersealing grouting is dopted in water bursting area of the roadway. Thus, the surrounding deformation can be controlled,and the water plugging result is obtained. The result showed that it hae remarkable technical economic benefits. The technology has been used in the water bursting area of the roadway.更多还原
