亭南煤矿二四盘区综放开采导水裂隙带高度探测与分析
Height Detection and Analysis of Fully Mechanized Caving Mining Water Conducting Fissure Zones of the Two Four Panel Area in Tingnan Coal Mine
摘要
Abstract
Tingnan Coal Mine is one of the typical mines in Binchang Mining Area that is prone to occur water inrush disasters due to the threat of the extra thick Luohe Formation sandstone aquifers in the strata.In order to master the destruction situation of the overburden rock after mining in the Two four Panel Area and effectively prevent and control the risk of water inrush in working faces,the height prediction and detection work of water conducting fissure zones are carried out.According to the existing conducting height estimation results based on the location of key layers in the panel area,it is concluded that the maximum conducting height can reach 208 m under the full thickness mining situation.Combined with the layout of working faces in the Two four Panel Area,Z1 borehole is designed for"two zones"detection.Through flushing fluid leakage and water level observation,it is concluded that the conducting height is about 207.5 m and the caving height is about 56.8 m,which is similar to the results obtained by using the water conducting fissure zone height estimation method based on the location of key layers.According to the detection results,the status of the goaf is analyzed,and the maximum height of the caving zone is calculated to be similar to the actual measurement.The exploration finds the occurence of severe destruction and caving situations of the bottom rock strata due to mining,but no large areas of roof hanging cavities are found.关键词
