摘要
针对倾斜煤层开采过程中开拓大巷的布置方式,设计了两种不同的方案,根据煤柱受到的应力作用及矿井上下山移动角的作用对煤柱的宽度进行计算;为保证煤产量,对比确定了最佳开拓大巷的布置方式,此时预留煤柱的宽度为30 m。
According to the layout of the development roadway in the mining process of inclined coal seam,two different schemes are designed.The width of the coal pillar is calculated according to the stress of the coal pillar and the movement angle of the mine.In order to ensure the coal output,the layout of the best development roadway is determined by comparison.At this time,the width of the reserved coal pillar is 30 m.
