| 摘 要： | 相邻工作面防水煤岩柱的宽度采用常规留设方法会导致煤柱尺寸留设过大，浪费勘探程度极高的煤炭资源.为解决这个问题，研究了相邻工作面防水煤岩柱常规留设方法，指出了导致防水煤柱留设过大的原因，在此基础上，将煤柱屈服区宽度计算公式引用到防水煤岩柱留设中，提出了煤柱和岩柱先分开计算、再整体考虑的方法，纠正了将岩移影响带宽度代替屈服区宽度的设计方法，缩减了所需留设煤柱的宽度，优化了整个防水煤岩柱设计.

| Abstract: | The routine method,which designed the width of waterproofing coal and rock pillar between two working faces,led to coal pillar size too big,and wasted the coal resources with extremely high degree of prospecting.In order to solve this problem,studied the routine design method of waterproofing coal and rock between two working faces,pointed out shortage of replacing the width of failure area and by displaced mass influence area.Formula of coal pillar failure area width was quoted in waterproofing coal and ro... |
