摘　　要：针对煤矿深水平高应力软岩机电硐室的严重底鼓情况,以淮北矿区邹庄煤矿-800m水平机电硐室为研究背景,依据弹性力学与塑性力学理论分析了底鼓的力学机理,同时基于围岩整体稳定性原理,制定了抑制底鼓的技术方案。现场实测数据表明该技术方案简便易行、效果显著,充分论证了研究成果的科学性和正确性。该成果不仅可以用于高应力软岩机电硐室底鼓控制机理与技术的研究,而且可以用于井下水仓、大断面高应力软岩巷道底鼓控制机理与技术的研究。Aiming at the serious floor heave in electromechanical chamber in high stress soft rock of deep mine,the-800 m level electromechanical chamber in Zouzhuang Coal Mine is taken as the engineering background,and a technical scheme for floor heave control is proposed based on the theoretical analysis of elastic mechanics and plastic mechanics of floor heave,and the principle of overall stability of surrounding rock.The field measurement data show that,the scheme is simple and effective,which fully demonstrates the scientificity and correctness of the research results.The results can be used in the control mechanism and technology research of floor heave not only in electromechanical chamber of high stress soft rock,but also in underground water bunker and large cross-section high stress soft rock roadway.
