摘要
陷落柱是我国北方煤矿机械化综采的主要障碍之一,在综采前探明采区陷落柱的位置和分布具有重要意义。本文介绍用于探测煤矿陷落柱的地震层析成像方法,并利用物理模拟的资料作成像试验,证实应用地震层析成像方法可以准确地圈定煤矿中的陷落柱。
Abstract
Collapsing pillars constitute one of the major obstacles in mechanized comprehensive coal mining in North China; therefore, it is of great significance to detect the location and distribution of collaping pillars in the working area before comprehensive mining. This paper introduces the seismic tomographic imaging method for detecting collapsing pillars in coal mines, and makes ima ging test with physical simulation data. It is proved that the seismic tomo graphic imaging method can be used to pinpoint collapsing pillars in coal mines.
