Research and application of geological model construction technology for intelligent mining
Intelligent mining of coal mine is the development direction of the future industry,and the construction of transparent geological model of working face is the basis.However,the precision of the current fine geophysical prospecting technology is not high,and the use of directional drilling,manual measurement and other methods costs a lot of manpower and material resources.The spatial position of the coal seam of the transparent working face constructed is not accurate enough to meet the needs of intelligent mining for geological information of the basic working face.Therefore,the geological model construction technology of multi-source data fusion and reinterpretation was pro-posed by using the interpretation results of 3D seismic data to fuse the geological information revealed by trough wave exploration,drilling geological radar,directional drilling,production and drilling.The technology was successfully applied in Jinjie Coal Mine of Shendong Coal Branch of China Shenhua Energy Co.,Ltd.,and the precision of the three-dimensional geological model of the working face was upgraded from"ten-meter level"and"meter level"to"sub-meter level".Based on this technology,the fully-mechanized mining face of Jinjie Coal Mine has realized intelligent cutting,and vigorously promoted the goal of unmanned and less human working face.
