摘 要

通过对金利石膏矿赋存条件以及矿山地质资料的研究，设计正确合理的开采方法尽可能的充分利用资源，避免浪费。金利石膏矿是在脉内采准切割，且脉内可剔除的废石夹层厚度最大为2m，因此该矿的贫化率很小，根据金利石膏矿的实际生产经验，矿山总的贫化率在3%左右。在石膏矿地下开采中，采场回采的夹石一般留在场内，可作为场内充填料，不运出地表，一方面降低运输成本，另一方面降低了矿石的贫化

针对金利石膏矿的赋存情况，完成矿山地下开采主要工程，金利石膏矿主要地下开采工程设计。阅读矿区地质概况地质构造矿床（层）特征矿石的结构构造矿床开采技术条件工程地质条件环境地质条件。主要建设方案的确定，包括：开拓运输方案、矿床的开采方式选择、运输方式、提升运输、回采矿量计算矿柱，回采和空区处理计算，并采用矿业软件或CAD软件绘制主要工程图，编制设计报告。

Abstract

By mine geological conditions and research data on the occurrence Jinli gypsum mine, correct and reasonable mining method design as much as possible the full use of resources and avoid waste. Jinli gypsum mine is in the vein of Mining cutting, and the inner pulse can eliminate waste rock interlayer thickness up to 2m, so the dilution rate of the mine is very small, based on actual production experience Kinley gypsum mine, the mine total dilution ratio at around 3%. Gypsum mine in underground mining, stope mining folder stone generally stay at the venue, the venue can be used as filling material, not out of the surface, while reducing transportation costs, on the other hand reduces ore dilution

Occurrence situation for Jinli gypsum mine, completing underground mining engineering major, major Jinli gypsum mine underground mining engineering. Structural configuration deposit mining conditions geological engineering geological conditions Environmental conditions read mine geology tectonic deposit (layer) characteristics of the ore. Major building programs identified, including: development and transportation programs, mining methods deposit choice, mode of transport, hoisting and transport back to the mining calculation pillar, mining and out area of ​​computing, using mining software or CAD software to draw the main drawing, preparation of design reports.

Key Words：Underground mining ,Gypsum Mine,Mining methods
