【摘要】：我国西南山区地质环境条件复杂,雨雪季节滑坡灾害频发,已经成为制约当地经济发展的重要因素之一。受2012年1月份降雨、降雪天气影响,迪庆矿业开发有限责任公司羊拉铜矿里农矿段的地表露天边坡、道路及矿山井下系统工程不同程度地遭到破坏,直接造成羊拉铜矿采掘失衡,矿山生产能力难于满足浮选厂和湿法厂的处理能力,为解决羊拉铜矿原矿供给量严重不足的问题,公司决定对羊拉铜矿KT6矿体进行开采,以提高矿山生产能力。结合目前3450中段、3390中段、3350等中段工程布置及现场地质调查情况,本次对3390中段开拓、采准系统及切割工程进行设计。该部分矿体的地质构造、开采技术条件较为复杂,应尽可能采用作业条件好,机械化程度高,采场生产能力大,矿石损失、贫化率低的采矿方法。在满足安全生产的前提下,充分利用原有井巷工程及供电、运输、供水和供风系统等,并结合羊拉铜矿生产能力现状,合理提高KT6矿体3390中段的生产能力、缩短建设周期。本文在研究分析了矿体的开采技术条件后,选了三种采矿方法进行比较,即“铲运机出矿无底柱阶段崩落法”、“振机出矿阶段崩落法”和“铲运机出矿有底柱阶段崩落法”。结合矿山生产实际情况,对上述三个采矿方案,从工程量、设各投资、优缺点等方面分别进行对比,设计采用铲运机出矿无底柱阶段崩落法回采KT6矿体3390中段47#-51#勘探线间的矿体,回采高度60m；采用铲运机出矿的无底柱浅孔留矿法回采51#-53#勘探线间的矿体,回采高度25m。3390中段开拓方式设计为“平硐+溜井”；通风方式采用侧翼对角式；生产供水利用已建成2座高位水池,不再新建高位水池；中段的涌水和作业废水汇集至3390中段运输平巷,由水沟自流排出地表,在中段平硐口设置澄清池,达标后排放。本次设计为KT6矿体的整体开采规划提供了技术指导。
[Abstract]:The complex geological environment conditions and frequent landslide disasters in southwest mountainous areas of China have become one of the important factors restricting the development of local economy. Affected by rainfall and snowfall in January 2012, the surface open pit slope, road and underground system works of Yangla Copper Mine Section of Diqing Mining Development Co., Ltd. were damaged to varying degrees. In order to solve the problem of serious shortage of raw ore supply in Yangla Copper Mine, the company decided to mine the KT6 orebody of Yangla Copper Mine because of the unbalance of mining in Yangla Copper Mine, and the production capacity of mine is difficult to meet the treatment capacity of flotation plant and wet process plant. In order to improve the production capacity of mines. Combined with the arrangement and field geological investigation of the middle section of 3450 middle section, this paper designs the development, mining and cutting system of the 3390 middle section. The geological structure of this part of orebody and the technical conditions of mining are more complicated, so the mining method with good working conditions, high mechanization degree, large stope production capacity, ore loss and low dilution rate should be adopted as far as possible. On the premise of satisfying the safety of production, the original shaft and roadway engineering, power supply, transportation, water supply and air supply system are fully utilized, combined with the present production capacity of Yangla Copper Mine, the production capacity of 3390 section of KT6 orebody is improved reasonably and the construction period is shortened. After studying and analyzing the technical conditions of ore body mining, three mining methods are selected and compared in this paper, namely, "caving method without bottom pillar stage of scraper drawing", "caving method in shaker drawing stage" and "caving method with bottom pillar stage" in scraper drawing stage. According to the actual situation of mine production, the above three mining schemes are compared in terms of engineering quantity, investment, advantages and disadvantages, etc. The orebody of 47#-51# exploration line in the middle section of KT6 ore body 3390 is mined by caving method without bottom pillar of scraper, the mining height is 60m, and the orebody between the exploration lines of 51 #-53# is mined by using shallow hole retention method without bottom pillar of scraper. The development mode of the middle 25m.3390 section of mining height is designed as "Adit pass well", the ventilation mode is flanking diagonal type, two high water pools have been built for production and utilization of water supply, and no new high water pools will be built. The water gushing and working waste water in the middle section of the middle section are collected to the transport lane of the middle section of 3390 and discharged from the surface by the ditch self-flow. The clarifier is set up in the middle section of the tunnel mouth and discharged after reaching the standard. This design provides technical guidance for the overall mining planning of KT6 orebody.
