煤巷锚索支护机理分析及其应用

Research on mechanics and application of deep coal road cable technique

结合高地应力、复合顶板等复杂地质条件,研究深井条件下煤巷锚索采用小孔径、施加高预应力的结构形式和施工工艺,工程实践表明,该技术是解决深井高应力软岩巷道、大断面交岔点等支护难题的有效途径。

The deep well coal road cable of small diameter hole and high pre-tension structure and craft were studied according to the condition of high stress and composite roof in coal mine.The result of the practical test showed that the technique was a effective way to solve the problems of high stress road and large span intersection supporting.
