请中译英下面一段话,"为确定沿空双巷合理煤柱宽度,以唐安矿3405综放工作面为工程地质技术条件,采用《FLAC3D》软件

In order to determine the rational coal pillar width along double gob-side entry,taking the 3405 fully-mechanized caving face of Tang’an Coal Mine as the technological conditions of engineering geology,the deformation law of the surrounding rock and plastic failure status under five different size conditions,i。e。the tunnel coal pillar being 2m,4m,8m,12m,and 20m are simulated and analyzed using FLAC3D software,and the stabilized control technology for surrounding rock which dynamic pressure is along double gob-side entry is explored through physical simulation。Through study it is held that adopting narrow coal pillar about 4m for the tunnel coal pillar is the most economical one in the same geologic conditions,and employing “beam net-cable integrated” supporting technology can effectively control the stability of the dynamic pressure along the double gob-side entry in different periods。
