【摘要】 1551(1)工作面位于潘一矿东部下山采区,为潘一矿13-1煤层保护层工作面。为了查明1551(1)工作面"地质异常带"的发育变化规律,利用三维地震动态解释系统依据波形强弱变化解释地质异常情况,但凭波形强弱变化解释无法判断"地质异常带"是无煤带还是地质构造及其边缘,根据1551(1)工作面下顺槽现场跟班实际探测的钻孔地质资料,结合11-2煤层顶板岩性赋存特征综合分析,准确的预测了"无煤带"的边缘,给领导决策及工作面安全开采提供了可靠的地质资料。为保护层回采及矿井的安全生产管理提供有效指导。比工作面在"无煤带"前做切眼多回采340m,多回采煤量约15.3万t,按t煤300元价值计算,为矿创造了4590万元经济效益,同时也扩大了13-1煤层被保护层开采面积,于此带来的安全与隐形的经济价值十分显著。更多还原

【Abstract】 1551(1)working face is located in the eastern mountain area of Panyi Mine, named Panyi Coal Mine 13-1 coal seam protection layer face. In order to find out the 1551(1)developmental rule of working face "geological anomaly zone", using dynamic 3D seismic interpretation system based on waveform can change the interpretation of abnormal geological situation, but with the waveform changing interpretation cannot judge "geological anomaly zone" is no coal zone or the geological structure and its edge, according to the 1551(1)working face along the drilling geological data slot. The actual scene detection, combining with comprehensive analysis of 11-2 Coal Seam Roof lithology occurrence characteristics, the accurate prediction of the "no coal zone" edge, provides reliable geological information for leadership decision-making and safe mining working face. To provide effective guidance for the management of production safety protection layer mining and mine. Work surfaces cut more than in 340 m in the "no coal zone", to the coal output is about 153000 tons, according to 300 yuan per ton of coal value calculation, created 45900000 yuan economic benefits for the mine, but also to expand the 13-1 coal seam is protective layer mining area, this bring security and invisible economic value very significant.更多还原
