摘要
运用相似材料模拟实验及数值模拟计算对浅埋近距离煤层群上行开采可行性进行分析.对下位煤层开采后覆岩运动与结构发育的分带规律、上位煤层所处状态的观测结果表明:下位煤层在受上位煤层的采动影响下,虽然有明显的弯曲下沉,但其整体连续性保持完好,可以上行开采。现场实测与分析结果吻合。
Apply similar material to conduct simulation test and also make numerical simulation calculation to analyze the possibility of as- cending mining in coal seam group with shallow burying and near interval.The observation result on covering movement after mining of lower seam,belt of structure development and state of upper seam shows that affecting by mining of upper seam,although evident bending and subsidence of lower seam occurs,its whole body and continuity remains perfect and ascending mining can be car...
