TieFa Limited Company Of Coal Industry (group) XiaoNan Second-level Prolong Optimization Proposition

The Mine's and deeply is an important subject to multilevel exploitingmining, which is the important link to guarantee mine's continue andbalance production in whole service issue. According as TieFa Limitedcompany of coal industry (group)XiaoNan concrete condition, At thefoundation of analyzing the mine's production and practices after puttinginto operation more than twenty years, combine with current scientifictechnological progress situation and its development, according to thescheme to second-level and extending proposition, optimization.Choosing a series of research for designing question , which guide TieFaLimited company of coal industry (group)XiaoNan 's second-level anddeeply prolong designing purpose.This thesis combine with geological condition of TieFa Limitedcompany of coal industry (group)XiaoNan 's well field, the characteristicof burying coal-seam, and production status of first horizontal, put forwardthe technically-feasible exploiting and deeply extending propositionfirstly, use method of optimizing to go on deeply analysis of technologicaleconomy and require for project period to the propose scheme, choosingthe optimum exploiting and deeply estending scheme, and carry on aseries of design and research work based on the optimum scheme.
