摘　　要：内蒙古上海庙矿区煤系地层极为松软,为解决矿井支护问题,对鹰骏一矿代表性岩样进行X衍射试验。从微观角度探究矿物成分,分析其地质性质,经观察在黏土矿物中以蒙脱石,高岭石为主,这些主要成分具有易亲水性,是影响岩石水理性质的重要因素。为了研究矿物水岩作用特性,进行了软化、崩解试验,分析岩石遇水后强度变化特点,了解质量与崩解次数的曲线特征关系。研究结果对于矿井建设及软岩巷道支护设计具有参考价值。The coal measures strata in ShangHai Temple Yingjun first colliery is broken ground. In order to solve construction of coal mines,Representative rock samples is tested by X-ray diffraction. Mineral compositon is studied from the microcosmic view. After observation on clay minerals, montmorillonite and kaolinite are the main microfactors that influence the water-rock physical properties, which are easy hydrophilic. Based on the soften experimental, The characteristics of the rock strength decreases are analyzed. The curve feature relationship between quality and the number of crumbing is investigated by the test of disintegration. The study is great value to the colliery construction and the design of soft rock roadway support.
