工作面顺槽二次破碎系统研究与应用

Research and Application of Secondary Crushing System in Working Face

现代综合机械化开采矿井已经普及,但工作面顺槽的布置一般只布置PLM型锤式破碎机负责对物料的破碎,物料最小粒度为300 mm,破碎后的物料经煤矿运输系统运至地面系统,再根据需要经破碎机加工,粒度达到50~150 mm。经综合研究,提出在工作面运输顺槽布置二次破碎系统的有益方案。

Modern comprehensive mechanized mining wells have been popularized, but the layout of the smooth grooves of the working face is usually arranged by the PLM type hammer crusher to break the material, the minimum particle size is 300 mm, the broken material is transported to the ground system through the coal mine transportation system, and then it is processed by the crusher according to the requirement, and the grain kangda to the 50 ～150 mm. is integrated into the comprehensive research. Puts forward a beneficial plan for arranging the two crushing system on the working face transportation trough.
