Abstract:
Based on the features of shallow buried depth and close distance coal seam group of Shendong Mining Area, some coal mines are covered with small coal mine fire area, and the fire area affects the safety work of underlying coal mining face. Taking the treatment of overlay small coal mines fire area about Shigetai Coal Mine 31 coal seam two panel mining face cutting hole as an example, based on the analysis of the impact range and degree of the small coal mines fire area on 31 coal seam two panel mining face ,and combined with coal seam occurrence conditions and mining technology in Shigetai Coal Mine, the treatment technology for shallow buried depth and close distance coal seam group mining overlying small coal mine fire area is researched, which provides technical support for safe mining of underlying coal mining face, improves the level of governance for small coal mine fire area in Shendong Mining Area, and further improves the comprehensive treatment technology system for shallow buried depth near horizontal and close distance coal seam group mining overlying small coal mine fire area.
