深部极复杂软岩新掘巷道支护技术研究

Study on Supporting Technology in Deep Soft-Rock New Digging Roadway in Extremely Complicated Conditions

以阳城煤矿新掘进巷道所处复杂地层为背景,结合软岩巷道支护理论与技术,对新掘进巷道采用锚喷、锚索和锚注、"长短锚"联合支护技术进行支护加固,取得了良好的支护效果,保证了巷道围岩的长期稳定。

Based on the background of the complex Strata in Yangcheng Colliery,new digging roadway,and combined with the support theory and technology in soft-rock roadway,the thesis analyzes the supporting technology of new digging roadway which including bolt-shotcrete,anchor cable and bolt-grouting combination supporting technique,long-short bolts combination supporting technique. The supporting effect is greatly and the long-term stable of the roadway was ensured.
