摘　　要：为有效治理坚硬顶板回采巷道动压影响下巷道底鼓,以同发东周窑煤矿5103回采巷道为研究背景,利用物理相似模拟试验验证了加强两帮支护强度及安装底角锚杆底鼓控制技术的可行性。现场工业性试验表明,底鼓控制方案安全可靠,为回采巷道底鼓控制提供实践经验。In order to effectively control the floor heave of roadway under the influence of dynamic pressure in hard roof mining roadway,the 5103 mining roadway of Tongfa Dongzhouyao Mine was taken as the research background,the feasibility of strengthening the support strength of two sides and installing the floor heave control technology of bottom angle bolt was verified by physical similarity simulation test.The field industrial test showed that the bottom drum control scheme was safe and reliable,which provided practical experience for the bottom drum control of mining roadway.
