高应力破碎顶板煤巷控顶卸压和三锚支护技术

The controlling broken roof by pressure relief and supported by rockbolt、anchor cable and bolt-grouting in high-stress coal drift

针对高应力破碎顶板煤巷中存在的支护问题 ,提出和分析了控顶卸压和三锚支护技术及其原理 ,并应用于陶阳煤矿高应力破碎顶板煤巷的支护实践 ,经过观测和对比 ,取得了较好的技术与经济效果 ,说明了控顶卸压和三锚支护技术能较好满足高应力破碎顶板煤巷的支护要求 。

According to the supporting problem existed in high-stress coal drift with broken roof, we put forward the theory and technology of controlling broken roof by pressure relief and of supported by rockbolt, anchor cable and bolt-grouting in high-stress coal drift. Furthermore, we applied them to TaoYang coal mine and obtained satisfactory effect by observation and comparison. It shows that the technology of controlling broken roof by pressure relief and support by rockbolt, anchor cable and bolt-grouting can meet the demand of support in high-stress broken roof coal drift. At the same time, it offers a new approach to coal drift support in complex condition.
