摘要
针对工作面开采过程中遇到的地质构造复杂、陷落柱内顶板破碎、底鼓等情况,通过采用钻探、巷探等技术手段,探明工作面情况,有针对性的制定工作面搬家的措施,为煤矿的高效安全生产提供了保障。
According to working face mining process, the construction may encounter complex geological structure, broken roof collapse column, floor heave, etc., the use of drilling exploration, roadway exploration and other technical means determined face situation, the development of targeted working face moving measures were settled, which guaranteed efficient production of mines.
