摘要
石灰石矿的地质和环境条件、穿爆工艺和设备、技术管理等因素是影响台阶爆破质量的几个主要因素,根底率与大块率为爆破质量管理的主要控制指标。在对地质和开采条件、设备和生产现状进行详细调查的基础上,分析了设备效率下降和生产成本上升的原因。通过采取一系列的技术和管理措施,改善了爆破效果,显著地降低了根底率与大块率,节省了开采成本。
In a limestone openpit mine,the main influence factors on the quality of bench blasting are geological and environmental conditions,technology and equipment of drillingandblasting and technical administrationThe yields of rocktoe and boulder are used as basic indexes for control of blasting qualityOn the base of investigating,in detail,the geological and mining conditions,the present situation of equipment and production,the causes for the drop of equipment efficiency and the rise of production cost are analyzedThrough taking a series of technical and administrative measures,the blasting effect is improved,the yields of rocktoe and boulder are obviously lowered and the mining cost is reduced
