摘要
针对深井沿空巷道护巷煤柱合理尺寸确定的问题，根据现场实际地质条件采用现场实测和数值计算的方法确定了协庄煤矿3416W工作面沿空巷道应留设小煤柱尺寸为2．5～4m，通过数值模拟分析，证明煤柱尺寸的确定是合理的，为类似条件下合理煤柱尺寸的确定提供了一种新方法。
According to the actual geology condition, the dimension of small pillar of roadway along gob in 3416w face in Xiezhuang Colliery is confirmed as 2. 5 ～ 4m with the spot observation and numerical simulation. The result of numerical simulation proves that the pillar dimension confirmed is reasonable and shows it a new confirmation method of pillar dimension in similar condition.
