Abstract
This graduate design is divided into two topics : one is open mining for Guan men shan iron mine, the other is underground mining for Dong sheng temple sulphur zinc.
1. Guan men shan iron mine opencast working. The output is 1600 thousand tons per year, service year is years .At first , I confirmed the slope safety angle, opencast ambit and the quantity of waste and mine. In this design, project can been as follows: road exploitation, excavator and self-uninstall auto. At last, this design has introduced these things as follows: open parameters, entrench, throughput, balanced proportion of shuck and exploitation and load technique, blast engineering, waste dump etc.
2. Dong sheng Temple sulphur zinc underground mining. The output is 850 thousand tons per year, service year is . development style is by gallery — blind incline shaft development ,mining way is shallow hole remaining ore, pulling style to ventilate. This design include well scope, reserves and well design. This design depicted the mine exploitation process(ventilation, drain, and power supply).
Key words : open mining; bench; development; underground mining.
摘要
本毕业设计包括两部分:关门山铁矿露天开拓开采和东升庙硫锌矿地下开拓开采。
:此矿的设计年产量是160万吨,。设计包括露天矿合理帮坡角确定,圈定露天开采境界,确定采场内有用矿物量和废石量。结合矿山发展和实际,选用公路运输,单斗电铲—汽车工艺,工作帮移动坑线开拓系统。另外,对开采参数与程序,掘沟,生产能力,均衡剥采比,爆破工程,采装工艺,排土,矿山工程进度计划等都做了简洁而清晰的叙述。
:此矿的设计产量是85万吨,。采用平硐—盲斜井开拓,无底柱分段崩落法采矿,抽出式通风。设计中还包括井田境界及储量、井筒、开采水平的设计等。
