摘要
针对祁南煤矿34下4综采工作面采用7.0 m×3.0 m的大断面开切眼,利用FLAC2D数值模拟软件,对综采工作面初次来压期间的应力分布规律进行了数值模拟,得到了工作面初次来压期间工作面的垂直应力及水平应力的分布规律,可为类似工程提供一定的指导意义。
In connection with using 7.0 m X 3.0 m large cross section open - off cut in the 34below 4 fully - mechanized coal mining face of the Qinan coal mine, it simulates the stress distribution during of the initial pressure for the fully - mechanized face by using the FLAC2D numerical simulation software. And the distrilmtions of the vertical and level stresses are got during the initial pressure, and can provide the some guidance for the similar projects
