摘要
为防止瑞龙煤业150201下综放工作面过腰巷发生片帮及冒顶等事故,通过对150201下综放工作面进行地质力学测试,并以测试结果作为制定过腰巷支护措施的依据,最后通过对工作面支架进行调斜、调整采高,使得工作面顺利通过了腰巷。
To prevent the rib spalling and roof fall during crossing waist roadway at 150201下underlying fully-mechanized caving face of Ruilong Coal Industry Co.,Ltd.,the author proposes the support measures through geological mechanics test by adjusting the support incline and the mining height to guarantee the smooth crossing the waist roadway.
