摘要
深部软岩巷道作为深部开采的主要难题之一,采用常规的支护方式往往难以取得预期的支护效果。破碎顶板巷道作为典型的软岩巷道之一,研究其合理的支护形式对我国进一步开发复杂地质条件下煤炭资源具有重要意义。以某矿11301工作面极破碎围岩为研究对象,以软弱围岩叠加拱承载体强度理论为依据,研究长短锚索支护技术在破碎顶板条件下支护效果,为破碎顶板巷道支护积累相关经验。
Deep soft rock roadway is one of the main problems in deep mining.It is often difficult to achieve the expected support effect by conventional support.The broken roof laneway is one of the typical soft roadways.It is of strategic significance to study its reasonable support form for the further development of coal resources under complex geological conditions in China.Based on the theory of the strength of the weak surrounding rock superposition arch bearing support,the supporting effect of the long and short anchor cable supporting technology under the broken roof is studied,and the relevant experience for the support of the broken roof laneway is accumulated on the basis of the strength theory of the soft surrounding rock superimposed arch bearing support.
