摘要
通过对新汶矿区深部煤巷两种支护形式围岩变形量的调查和对锚杆支护方式围岩变形量概率统计分布的研究 ,分析了不同条件下两种支护方式的适用性、得出了锚杆支护方式下的围岩变形规律。对新汶矿区深部煤巷支护形式的和支护参数的选择具有一定的指导意义。
By means of investigating surrounding rock deformation of two roadways support forms in deep mining for Xinwen coal mine area, and after studying probability distributing of surrounding rock deformation under rock bolting pattern, the applicability of two support patterns under different conditions is analyzed, and the rules of surrounding rock deformation under rock bolting patterns is obtained. It is of directive signification for choose roadway support forms of deep mining and support parameters for Xinwen coal mine area.
