梧桐庄煤矿导水陷落柱的计算机辅助辨识

隐伏导水陷落柱的辨识一直是梧桐庄煤矿,乃至华北型煤矿水害防治的难题,因此寻求导水陷落柱的辨识方法,防止恶性突水事故的发生,便成为该矿安全开采的关键.本文通过对矿区水文地质条件、温度场、应力场的详细分析,建立了水源判别模型,探索了一条水文地质复杂型矿山导水陷落柱辨识的途径,并成功地识别了1号和3号强导水陷落柱,避免了两次突水淹井灾害.

Computer Aided Identification of Conductible Sinking Column In Wutongzhuang Coalmine

To identify conductible sinking column has been a hard problem in Wutongzhuang Coalmine, even in whole north China Coal Field. To solve the problem become the key to preventing serious water hazards in coalmines and ensuring safety for mining activities. In this paper, a new approach to identifying conductible sinking column for the coalmines with complicated hydrogeological conditions is discussed by analyzing the hydrogeological conditions, temperature field, stress field and water resource distinguish modeling. The method was successfully applied to identifying No. 1 and No. 3 conductible sinking column in Wutongzhuang coal nring and 3 serious water hazards were avoided.
