摘要
根据孟加拉国巴拉普利亚煤矿1210工作面的实测资料,利用UDEC数值模拟软件,单层开采5 m情况时,模拟计算首分层~六分层开采后覆岩最大导水裂缝带的高度;单层开采10 m情况时,模拟计算首分层~三分层开采后覆岩最大导水裂缝带的高度。通过与经验公式计算结果进行分析对比,给出了硬顶板条件下分层开采导水裂缝带高度发育的计算公式。
According to the measured data of the face UDEC numerical simulation software is used to study 1210 of Balapulia coal mine in Bangladesh, the the maximum height of the diversion tunnel, in the case of the single layer mining 5 m and 10 m. Based on the analysis and comparison of the empirical formula, the calculation formula of the height development of the aqueduct in the sub - bed under the condition of hard roof is given.
