摘要
分析白庄煤矿围岩地层结构的基础上,进行了岩石力学参数测试和围岩稳定性分类,得出该矿7100轨道巷属于典型的"不稳定围岩巷道(Ⅳ类)"。针对此巷道类型提出了复合支护方式,并对反底拱支护能力进行了分析,复合支护方式可以使围岩支护体形成封闭式结构,从而有利于提高巷道支护效果。
On the basis of Baizhuang coal mine surrounding rock formation structure, classify rock mechanics parameters testing and surrounding rock stability, draw a conclusion that 7100 mine track drift belongs to ＂ instability surrounding rock roadway （ IV type）＂ Aimed at this type of drift, raised composite support method, and analysis of anti - inverted arch support capacity, the composite support methodcould make surrounding rock support to be close - ended structure,in order to improve the effect of drift support.
