摘要
为解决唐口煤业公司1303孤岛工作面应力集中快速解危问题,通过对工作面煤粉量监测、煤体应力变化和大直径钻孔施工等数据综合分析,得出快速解危工程与大直径钻孔卸压参数之间的关系,对孤岛工作面快速掘进具有指导意义。
in order to solve the coal companies Tangkou 1303 isolated working face stress concentration problem should get fast, comprehensive analysis of the data changes and large diameter drilling construction of monitoring, coal working face coal, obtains the fast controlling engineering and large diameter bored relationship between pressure relief parameters, is of guiding signiifcance for rapid excavation of isolated island working face.
