摘要
留设保护煤柱是为了使井田内重要保护对象在保护范围内,不受采动影响。垂直剖面法适用于条形建筑物保护煤柱的设计。龙泉煤矿在井田内线路保护煤柱的设计过程中,将复杂计算公式用函数分解编入Excel2003制成自动计算表格,大大提高了计算的准确性,取得了较好的效果。
The protective coal pillar is important in order to make the object within the field of protection within the scope of protection, not affected by mining. The vertical section method is suitable for the design of coal pillar for protection of buildings in Longquan coal mine. The strip line in the coal pillar in the design process, the complicated calculation formula of function decomposition into 2003 made automatic calculation form, greatly improve the accuracy of the calculation, and achieved good results.
