摘要
煤柱的参数变化直接影响条采工艺煤柱对地表沉降控制效果。通过数值模拟,以级索煤矿16E108工作面为工程背景,设定了煤柱宽度为8、10、12 m三种模拟方案,分别对各方案竖直运移量、地表倾斜、下沉等参数进行分析。研究结果表明:随充填条带宽度的增大,地表竖直下沉、水平变形(绝对值)、倾斜、曲率逐渐减小,为选择合适煤柱参数提供借鉴。
The width change of coal column parameters affects ground subsidence control effect, 16E108 working face of Jisuo Mine was taken as engineering background, the width of coal column was set as 8、10 、12 m by numerical simulation,parameters of vertical migration quantity, surface incline and subsidence of each plan were analyzed. The result showed that ground vertical subsidence, level deformation（absolute value）, inclination, curvature decrease as the increasing of width of filling strip, which provides reference for reasonable parameters settlement for coal column.
