摘要
Abstract
With the advancement of fine coal exploration and the deepening of mine water hazard prevention and research, more and more advanced test instruments and detection methods are introduced into the study of engineering rock mass. In this paper, the samples of mudstone and sandy mudstone cores of Jurassic Anding, Zhiluo and Yan'an formations on the roof of Huanglong coal layer are selected, and the mineral composition and microstructure characteristics of the rock mass are mastered by means of X-ray diffraction and scanning electron microscope. The disintegration and expansibility tests of the rock mass are carried out to clarify the hydraulic properties of several types of rock mass. The intrinsic relationship among mineral composition , microstructure and the hydraulic properties of rock mass is analyzed objectively, which provides basic data and theoretical basis for the research and prevention of roof water hazards in the study area, and provides a reference for the comprehensive evaluation of water-resisting and waterproof properties of Jurassic coal measures strata.关键词
