摘　　要：新疆煤系地层以弱胶结地层为主,弱胶结岩石普遍具有胶结松散、力学强度低和水软化作用明显的特点,弱胶结地层给煤炭资源开采带来极大困难。结合新疆弱胶结地层地质条件,采用相似模拟实验方法,分析了膨胀应力在此类巷道围岩变形过程中的影响,研究了弱胶结地层富水巷道围岩变形规律,为西部矿区类似工程地质条件下巷道变形规律研究与工程支护设计提供有益的参考。The coal measure strata in Xinjiang are mainly weakly cemented strata,weak cemented rocks are generally characterized by loose cementation,low mechanical strength and obvious water softening.The weak cementation stratum brings great difficulty to coal resource exploitation.Combined with the geological conditions of weakly cemented strata,the influence of expansive stress on the deformation process of the roadway surrounding rock is analyzed by similar simulation experiments,and the deformation law of water-rich roadway surrounding rock in weakly cemented strata is studied.Research provides a useful reference for the study of roadway deformation law and engineering support design under similar engineering geological conditions in western mining area.
