陈四楼矿1.5 Mt-a新井初步设计 浅析采煤工作面断层处灾害机理及防治.docVIP

第 PAGE 52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。 一般部分为陈四楼1.5 Mt/a新井设计。陈四楼煤矿位于河南省永城市西北郊区，交通较为便利。井田倾向（东西）长约3.80 km，走向（南北）长约5 km，井田总面积为19.00 km2。主采煤层为2号煤层，平均倾角为9.73°，煤层平均厚度为7.43 m。井田地质条件较为简单。 井田工业储量为206.49 Mt，矿井可采储量125.13 Mt 。该矿井服务年限为64.17 a，涌水量不大，矿井正常涌水量为894 m3/h，最大涌水量为1200 m3/h。矿井瓦斯涌出量较低，为低瓦斯矿井。 井田为立井两水平开拓；长壁放顶煤采煤法；矿井通风方式为中央并列式。 矿井年工作日为330d，工作制度为“三八”制。 一般部分共包括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.准备方式-盘区巷道布置；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。 专题部分的题目为浅析采煤工作面断层处灾害机理及防治，主要针对断层处灾害机理，提出了部分防治措施。 翻译部分主要内容长壁开采老空区上部地表残余变形的机理与控制，英文题目为：Mechanism andcontrol of ground residual deformation over longwall goaf。 ABSTRACT This design includes of three parts: the general part, special subject part and translated part. The general part is a new design of Chensilou mine. Chensilou mine lines in north-west of Yongcheng in Henan province. The traffic of road and railway is convenience to the mine. The width of the minefield is 3.80 km ,the width is about 5.00 km，well farmland total area is 19.00km2.The two is the main coal seam, and its average dip angle is 9.73 degree. The thickness of the mine is about 7.43 m in all. The proved reserves of the minefield are 206.49 Mt. The recoverable reserves are 125.13 Mt. The designed productive capacity is 1.5 Mt percent year, and the service life of the mine is 64.17 years. The normal flow of the mine is 894 m3 percent hour and the max flow of the mine is 1200 m3 percent hour. The mineral well gas gushes the deal lower, for low gas mineral well. The well farmland is two levels in vertical shaft development;the cole mine is the longwall mining;the centralized ventilation. The working system “three-eight” is used in the Chensilou mine. It produced 330 d/a. This design includes ten chapters: 1.An outline of the mine field geology; 2.Boundary and the reserves of mine; 3.The service life and working system of mine; 4.development engineering of coalfield; 5.The layout of pan
