Feasibility Exploration of Arranging Boundary Crossheading under Complex Geological Conditions in Songhe Coal Mine
In order to solve the problems of mining and excavation mismatch,and the difficulty in recycling boundary resources under the complex geological conditions of large dip angle and high gas content in Songhe coal mine,this paper were systematically analyzed the engineering geological conditions of the mining area.Combined with the current mining and excavation engineering layout of the mine,factors such as coal seam resource conditions,topographical and geological conditions,resource reserves and value,and the existing status of the original shaft engineering were comprehensively considered.Based on the existing mine design,this paper designed and arranged the boundary crossheading of the third section of Songhe coal mine,exploring the scientific and reasonable layout of mining and excavation engineering under complex geological conditions,providing guarantees for the formulation of production development plans and technical transformation of Songhe coal mine,and assisting in the high-quality development of the mine.
