新源煤矿0.9Mta新井设计.doc

1、 第V页摘 要本设计包括三个部分：一般部分、专题部分和翻译部分。一般部分为新源煤矿0.9Mt/a新井设计。共分10章：1.矿区概述及井田地质特征；2.井田境界和储量；3.矿井工作制度及设计生产能力、服务年限；4.井田开拓；5.准备巷道布置；6.采煤方法；7.井下运输；8.矿井提升；9.矿井通风与安全技术；10.矿井基本技术经济指标。矿井工业场地位于山西省沁源县西部李元镇附近，距沁源县城约17km，行政区划隶属于山西省长治市管辖。井田南北宽4.35.6km，东西长2.823.23km，面积约17.88km2。主采煤层为2号煤，2号煤平均厚3.0m，井田地质条件简单。矿井工业储量为70.683Mt

2、，可采储量53.753Mt。矿井正常涌水量为7.5m3/h，最大涌水量为10.83m3/h。矿井瓦斯涌出量低，为低瓦斯矿井。矿井为立井单水平开拓，大巷采用胶带输送机运煤，辅助运输采用无极绳绞车，矿井通风方式为中央并列式通风。矿井年工作日为330d，每天净提升时间16h。矿井工作制度采用“三八”制，两班生产、一班准备。专题部分题目是复合顶板下的回采巷道支护技术研究。翻译部分主要内容是以兖州煤矿的现状为基础，通过对煤层突水风险的评估，总结出经验公式以确保较深部煤层开采的安全。英文题目为：Comprehensive evaluation of water-inrush risk from coal

5、ms.Xinyuan mine is located nearby Liyuan of Changzhi in Shanxi province. The length of the mine field is 4.35.6 km，the width is about2.823.23 km，and the total area is17.88 km 2. The No.2 coal seam is the main coal seam，The thickness of the three main coal is about 3.0m respectively. The geologic str

6、ucture of this coalfield is simple. The normal flow of the mine is 7.5 m3 percent hour and the max flow of the mine is 10.83 m3 percent hour. The mineral gas gushes the deal lower, and it is a low gas mineral mine.The mine is a single level in two shafts to develop. The central laneway uses Belt Con

7、veyor to transit coal, and trolley wagons are used for accessorial transportation in the roadway. The ventilation mode of this mine is center juxtapose form. The “three-eight” working system is used in the Xinyuan mine. It produces for 330 days a year.Special subject part of topics is Analysis and C
