直线掏槽技术及合理炮孔深度的确定

Burn Cut Technique and the Determination of Reasonable Hole Depth

掏槽方式及布孔参数影响着掘进效率和成本。通过理论计算与现场实践确定了合理的炮孔深度及其它参数,在原有装备水平的条件下,通过调整生产组织,提高了掘进工效,降低了掘进成本。

The cut way and hole parameters affect the drivage efficiency and cost. Reasonable hole depth and other parameters are determinated by theoretical calculation and production practice. Through adjusting and organizing production,the drivage efficiency is improved and drivage cost is reduced on the basis of tormer equipment level.
