切割阻力测试和汽车性能测试探讨

Discussion on testing of Cutting Resistance and Truck Performance

随着五大露天煤矿的开发,国外大型采矿运输设备的引进,迫切需要了解适合于我国煤田地质条件的采矿工艺、采掘运输设备和使用、管理、维护的信息。几年的实践证明,这些信息仅参考外国的经验和一般的理论分析或统计资料已满足不了现代化生产的要求。

this paper concentrates on testing of cutting resistance in reck and coal and testing of truck performance. It is one of the important means for planning, production and research departments in selecting oplimal open-cast mining technology and transporting equipment. Examples are given to illustrate that the mining and technical parameters and curves showing their relations obtained in the site tests can be used as criteria for planning optimal mining technology, selection, introduction and use of equipment by taking into account the geological conditions in the Chinese coal field. And the method of simply referring to the experience abroad, the general theoretical analysis of compressive strength or analysis of statistic data can not satisfy the need of modernized production.
