浅埋深近距离煤层开采上覆小窑火区治理技术
|
摘要
基于神东矿区浅埋深煤层群开采的特点,且部分矿井上覆存有小煤窑火区,影响下分层工作面的安全生产。以石圪台煤矿31煤二盘区工作面切眼上覆小窑火区治理为例,在分析小煤窑火区对31煤二盘区工作面影响范围及程度的基础上,结合石圪台煤矿煤层赋存条件及开采工艺,研究优选出适合浅埋深煤层群开采上覆小窑火区的治理技术,为下分层工作面的安全开采提供技术保障。治理技术提升了针对神东矿区小窑火区的治理水平,进一步完善浅埋深近水平煤层群开采上覆小窑火区的综合治理技术体系。
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.
