| 摘 要： | 针对阳煤集团新元公司采动剧烈的垮冒煤巷普遍存在顶板严重下沉、巷帮严重臌帮和巷道底鼓等问题,对煤柱支承压力进行了现场实测和计算机三维数值模拟,分析研究采动剧烈影响下的煤巷支承压力分布规律,得出应力集中系数平均值达3.2及煤巷支承压力的分布范围,从而为采动剧烈垮冒煤巷的支护方案设计提供科学依据。

| Abstract: | Aiming at the problems such as roof severe subsidence,the ribs of roadway ingression and floor heave in roadway of Yangguan coal industry Co.Ltd Xinyuan corporation,abutment pressure of coal pillars are analyzed by field measurements and 3D numerical simulation to research on the distribution law of abutment pressure in the mining-induced violently collapse coal roadway.The average value of stress concentration factor is 3.2,and the abutment distribution scale is obtained.These results can supply the scientific basis for the supporting scheme design. |
