摘要
煤矿井下复杂多变的地质构造对综采工作面的推进产生重要影响。为保证工作面顺利通过地质构造变化断层带,杜绝漏顶冒顶事故,实现矿井的安全高效开采,以六合煤业为例,通过采用无线电波坑透技术对该矿区2503综采工作面进行超前探测,查明落差大于1/2煤厚的断层和长轴大于20 m的陷落柱的分布情况,为工作面的采掘和支护工作提供科学依据。
The underground complex geological structure exerts great influence on fully mechanized working face advancing, in order to make working face cross the fault with geological structure change, avoid roof caving and realize safe and efficient mining, Liuhe Mining Industry was taken as example, the 2503 fully mechanized working face was detected in advance by radio wave penetration technology, it was found that the distribution of the fall of fault bigger than 1/2 coal seam and long axis of collapse coal column bigger than 20 m were explored, provided scientific data for mining and support of working face.
