摘要
针对阳泉矿区马家坡新村房屋破坏情况 ,应用山区开采沉陷预计系统 ,选取 2个工作面、 4条预计线进行预计 ,指出目前规程有关山区保护煤柱设计中不考虑地形变化 ,而单纯减小移动角并不完全正确。
In view of the damage to buildings of Majiapo new village in Yangquan mining area,the predication system of mining subsidence on mountain area is applied to predict four prediction lines which is related to two working faces that are near the coal safety pillar.It is concluded that simply reducing the values of the angle of movement while ignoring the variety of terrain are unadvisable,when safety pillars in mountain area are desingned according to actual regulations.
