摘要
针对某煤矿区段煤柱尺寸优化问题,通过理论计算法确定了合理区段煤柱留设尺寸范围。提出留设煤柱的原则不是追求最小变形,而是允许适当变形,最终实现安全经济的和谐统一原则。遵循此原则,通过数值模拟,最终确定了煤柱尺寸为20 m。
Aiming to section coal pillar size optimization problem of a mine,through the theoretical calculation method to determine the reasonable section pillar size range. Putting forward the principle of remaining pillar is not to pursue the minimum deformation , but to allow acceptable deformation which will lead to realizing the sale and economic harmony finally. Following this points,through numerical simulation, ultimately determines the size of coal pillar is 20 meters.
