巩义鑫 China Machinery Mining Knowledge Forum COLLECTION: spatial characteristics of the ore body means the ore body in three-dimensional space has features, such as ore body shape, occurrence, width, thickness, depth of burial and so on. These factors inherent in ore deposits in ways largely determine the development and utilization. Depth of burial is decided Deposits opencast or underground mining. In general the cost of open-pit mining is lower than underground mining. But this is not necessarily proof Li claw loaders, which depends on the specific conditions of occurrence deposits. Deposits although some shallow due to a large amount of stripping rock, its cost is not economical than underground mining, have mined using underground. Of course, some buried deep slag deposits in the machine, it can only be underground mining machinery mining 巩义鑫 China Knowledge Forum: Principles select mining methods followed. According to the characteristics of deposits in ore grade level of proof slag machine parameters, the degree of uniformity and optional features, according to the known deposits in the exploitation of similar quality indicators mine, with several groups of the lowest grade and industrial grade boundaries, choose a representative area deposits Savings were calculated and average grade, and according to national needs, the degree of resource utilization, production scale, mining, ore processing technology using coal slag machine conditions, production costs, investment results and other factors, for each set of indicators comprehensive comparison program Select one of the most reasonable option.
