济宁三号煤矿7.0Mta新井设计.docx

1、摘 要本设计全篇有三个部分：一般部分、专题部分和翻译部分。一般部分为济三矿7Mt/a井型设计。济三煤矿位于山东省西南部，交通便利。井田走向（东西）长约8km，倾向（南北）长约7.5km，井田总面积为55km2。主采煤层为3上、3下及16上号煤，平均倾角为4，煤层平均总厚为10.21m。井田地质条件较为简单。井田工业储量为91954万t，矿井可采储量66020万t。矿井服务年限为72.55a。矿井涌水量较小，矿井正常涌水量为240m3/h。矿井瓦斯涌出量为0.65m3/t，为低瓦斯矿井。煤层具有自然发火倾向。井田为立井单水平开拓，水平标高-540m。矿井采用盘区式准备方式，主运输大巷采用胶带运输

2、机运煤，辅助运输采用无轨胶轮车设备。矿井通风方式为中央并列式通风方式。矿井采用放顶煤采煤方法，采3.6m放5.66m。矿井年工作日为330d，工作制度为“四六”制。日循环进九刀，截深0.865m。专题部分题目是“深部巷道变形机理及支护技术分析”。主要分析我国深部巷道在高应力的状态下所表现的变形特征，以及如何针对不同的条件选择适当的支护时机采取不同的支护方式。翻译部分主要内容为关于破碎软岩巷道变形特征分析，英文题目为：Deformation characteristics of surrounding rock of broken and soft rock roadway。关键词：济三煤矿设计

3、；软岩巷道；变形特征ABSTRACTThis design consists of three parts: the general part, the special part and translated part.The general part is a new design of JiNing NO.3 mine. Jining mine lines in Southwest of Jining in ShanDong province. The traffic of road and railway to the mine is very convenience. The geol

4、ogical structure of this area is simple. It is about 8 km in the run from the north to the south of the minefield, and It is about 8 km in the run from the east to the west of the minefield. The area is 60km2.The third and the sixteen seam is the main coal seam, and its dip angle is 4 degree. The th

5、ickness of the mine is about 10.21m in all. The proved reserves of the minefield are 919.54 million tons. The recoverable reserves are 660.20 million tons. The designed productive capacity is 7 million tons percent year, and the service life of the mine is 72.55 years. The normal water inflow of the

6、 mine is 240 m3 percent hour , and the gas outflow is 0.65 ml/g， and the mine is low gaseous mine. The caol seam is self-ignition in nature.The field has been divided two mining levels. The first level should be located at the lever of -540m, which use raise and dip mining method of vertical shaft d

7、evelopment. The main shaft skip install skip and the auxiliary shaft install cage. The main entry transportation of the coal is using with the belts, and the auxiliary entry is using of track and rubber tyre car.In the earlier stage, the system that wing ventilation is located at the center is used

8、in the mine. In the later stage, the system that wing ventilation are locted at the boundary is used in the mine. The caol mining is excating seam in 3.6m and releasing seam in 5.66m.In the Jining NO.3 mine, there are three four teams each day, and each work team works six hours. It produced 330d/a.

9、The topic of the special part is stratification mining of thick seam and determining reasonable position. Main analyse the deep roadway in a state of high stress deformation characteristics shown, for different conditions and how to select the appropriate supporting opportunity to take a different s
