摘要
采用理论研究、离散元数值计算分析了冲击地压煤巷破坏机制 ,研究了冲击地压条件下煤巷锚杆支护机理 ,利用数值分析方法确定了锚杆支护形式及支护参数 。
With a theoretic study and a calculation of discrete element value, the paper analyzed a failure mechanism of a pressure bump seam roadway. The paper studied a bolt support mechanism in seam roadway under a pressure pump condition. With a value analysis method, the paper has set up a bolt support form and support parameters. The support technology has been applied in the seam roadway with a high potential of pressure bump.
