神东矿区浅埋深薄基岩上覆厚松散层水害治理
Water disaster control in overlying thick loose layer on bedrock in Shendong coal mining area
摘要
Abstract
Shallow burial depth, thin overlying bedrock and thick loose aquifer are the basic geological character-istics of Shendong mining area. During stoping, especially after breaking of the first main roof, water and sand in-rush is easy to happen. In order to realize safe stoping, this paper took the cutting area of working face 12207 in Shangwan coal mine as the experiment object, researched the height of caving zone and water conducting fractures, the height of water/quicksand-proof coal/rock pillars, and predicted the mine inflow. Accordingly, several measures were taken including hydrogeological supplementary investigating, construction of direct water drainage holes, underground water detection and drainage as well as surface grouting to guarantee the safe stoping.关键词
