综合勘探技术在采煤工作面构造发育区精细化探测中应用

The Application of Comprehensive Exploration Technology in the FineExploration of Coal Mining Face Structure Developing Area

回采工作面开采范围内地质构造探测对实现煤炭安全高效回采具有显著促进意义。文章以50306综放工作面回采为例,将以加密无线电坑透+钻探(钻孔窥视)技术为核心的综合勘探技术应用到采面构造发育区精细化探测中。现场应用表明,现场探测确定的构造发育区位置及类型与采面回采揭露地质构造类型一致;综合勘探技术可实现采面构造发育区精细化探测,探测成果可在一定程度上指导煤炭生产效率并提高安全保障能力。

The exploration of geological structure in the mining area of working face is of great significance to realize safe and efficient coal mining.Taking 50306 fully mechanized top coal caving face as an example,this paper applies the integrated exploration technology,which is based on the technology of infill radio pit penetration and drilling(drilling peep),to the fine exploration in the structure developed area of the mining face.The field application shows that the location and type of the structure development area determined by field survey are consistent with the geological structure type revealed by mining face,and the comprehensive exploration technology can realize the fine detection of the structure development area in mining face,the detection results can guide the coal production efficiency and improve the safety guarantee ability to a certain extent.
