摘要
坪湖煤矿657综采工作面三巷在遇落差为2.3～6.6m的正断层时,通过对断层走势的分析与割采方案的确定,采用按+14°坡度向前提溜移架的操作和运用人力资源、地质测量、通风防火以及生产安全上的技术措施,成功、快捷地采过了断层。
In the process of triple-- entry＇s encountering a normal fault with a fall of 2.3 to 6.6 m in 657 fully mechanized working face of Pingfu Colliery, the authors propose the technical measures of advancing support forward in ＋14°gradient to cross the large fault successfully and rapidly by applying human resources, geological survey and fire prevention with ventilation.
