基于數(shù)值模擬的深井開采地表巖移范圍圈定

〔摘 要〕運用數(shù)值模擬方法，通過提取計算模型地表節(jié)點位移數(shù)據(jù)、計算地表變形、生成地表位移云圖和沉降等值線等做法，對某超大規(guī)模深井礦山的地表移動范圍進行了圈定。與傳統(tǒng)方法相比較，數(shù)值模擬充分結合了礦山開采工藝，減少了礦山的征地面積，為深井開采地表移動范圍的圈定提供了一定的參考價值。

Abstract  The surface movement range of a super-large scale deep mine was delineated by using numerical simulation methods， such as extracting displacement data of surface in the calculation model， calculating surface deformation， generating surface displacement cloud maps and settlement contour lines， and other methods. Compared with traditional methods， numerical simulation fully integrates mining process， reduces the land acquisition area of the mine， and provides certain reference value for delineating the deep mining surface movement range.

地下礦山開采以后，原巖應力場的平衡被打破，巖體中的應力重新分布，從而引起圍巖的變形、位移、開裂、冒落，甚至產生大面積塌陷。（剩余4406字）
