摘要
护巷煤柱宽度的留设直接关系到工作面的生产安全。结合理论经验公式计算出煤柱留设理论宽度,并根据实测分析出不同煤柱宽度下支承压力分布规律,应用弹性核理论得出实际护巷煤柱宽度。通过理论计算与现场实测相结合的方法,最终得出寸草塔矿护巷煤柱的合理宽度为15 m。
The rational width remained to the chain pillar is directly related to the safe production of the working face. In this paper, the theoretical width to be remained to the chain pillar was calculated with the empirical formula, the distribution law of the bearing pressure in different coal pillar width was analyzed according to the site measurement, and the actual width of the chain pillar was obtained by using the elastic core theory. Based on the theoretical calculation and the field measurement, it came to the conclusion that the rational width of the chain pillar is 15 m.
