保证高效率连续生产的采金船开采法,在苏联是得到广泛普及的砂矿床开采方法.其特点是不能直接研究通常的影响因素和挖掘参数对彻底回采矿砂的作用.由于移步距之间的开采损失值没有足够的根据,因此其值在采金船开采设计时取假设值,用清理已确定的被采面积的方式来弥补这些不足.按照清理底板的要求,超挖深度应当不小于0.2米.在矿山开采技术条件经常变化的情况下,提高清底参数设计的可靠性和理论性对预知质量损失值来讲具有重要意义,其方法就是建立经济一数学模型的方法.
The mining method of gold mining vessels which ensures high efficiency and continuous production is widely used in the Soviet Union for the exploitation of sand deposits characterized by the fact that the usual influencing factors and the effect of excavation parameters on the complete recovery of ore can not be directly studied. The value of the mining loss between the lack of sufficient basis, so the value of mining gold mining ship designed to take the assumed value, with clean-up has been identified by the mining area to make up for these deficiencies.According to the requirements of clean-up floor, the depth of digging should not Less than 0.2 meters.It is important to improve the reliability and theoretical design of clear-cut parameters in predicting the mass loss value under the condition of frequent changes of mining technology conditions, and the method is to establish the economic-mathematical model.
