摘　　要：随着煤矿充填开采技术的不断发展,充填体力学已成为充填开采的重要组成部分。通过测试不同石灰比条件下(分别为11∶3、10∶4、9∶5、8∶6)高浓度胶结充填体试样的单轴抗压强度,研究了充填体强度变化规律及其力学特性,并分析了充填体与顶板、侧向围岩及底板之间力学作用关系。With the development of filling technology of coal mine, filling mechanics had become an important part of filling mining. Tested the uniaxial compressive strength of high concentration cemented filling sample under different ratios of coal gangue and fly ash 8：6）; studied the strength change laws and mechanical properties of the mechanical effect of the filling body on the roof, lateral rock and floor. （respectively 11：3, 10：4, 9：5, filling body; and analyzed the
