摘要
巷道围岩控制是深部资源开采中的关键问题,而要攻克深井软岩巷道支护的难关,就必须首先研究底鼓的机理及其防治措施。在大量现场研究、实验室模拟实验和数值计算的基础上,探讨了巷道底鼓的基本特征,分析了4种类型底鼓的机理及影响因素,综述了我国近年来防治底鼓的有关研究成果,最后介绍了2个防治巷道底鼓的实例。
The deformation control of surrounding rocks is one of the key problems in deep mining. Only when the mechanism and control methods of floor heave are correctly understood, the difficult problems in the support of roadways in soft rocks of deep mines can be solved. Based on the field investigation, model tests and numerical simulation, the features and mechanism of four kinds of floor heave of roadway in deep coal mining are discussed, the major factors affecting the floor heave are analyzed, and recent advance of control methods of floor heave in coal mines, including two cases in China, is summarized.
