钻爆法掘进与掘进机掘进施工方式的优化探讨

Discussion on optimization of drilling and blasting heading and roadheader heading

对钻爆法掘进与掘进机掘进的方式进行比较,以取得最优效果。掘进方法的选择应考虑的主要因素包括:岩石抗压强度、岩层对掘进机的支撑条件、运输及装配条件等。掘进系统的经济性很大程度上取决于岩石的种类、抗压强度及共磨蚀性。实践证明,每种掘进系统在一定的使用条件下都可以最佳地进行作业。

In order to have the optimized benefits, the paper had a comparison between the drilling and blasting heading and the roadheader heading. The main factors to select a heading method shall mainly be including the rock compressive strength, the support condition of the roadheader to the strata, transportation and assembling condition. The economics of the heading system were greatly dependent on the rock types, compressive strength and abrasion. The practical application proved conclusion of the paper was that each heading system could have a optimized operation under the certain application condition.
