长平四矿3.00 Mta新井设计.doc

1、摘 要本设计是长平四矿3.0Mt/a新井设计，设计矿井为一井一面的高产高效矿井。长平四矿位于山西省高平市西面，交通便利。井田走向长度约5.0km，倾向长度约3.8km，井田总面积为18.94km2。通过对地质资料的深入分析，采用立井单水平开拓方案。主井、副井和风井均位于井田中部，采用中央并列式通风。井田内有三个煤层，且间距小，煤层倾角平均6左右。根据煤层赋存条件和井田地质构造特点，采用岩层大巷布置，通过斜巷进入煤层，井底车场位于+410m岩层中。采煤方法采用倾向长壁采煤法。，工作制度为“三八”制,矿井年工作天数为330日。在设计中，对大巷的布置方式进行了技术经济比较。全矿分为四个带区和一个盘区

2、。采用跳采，沿空掘巷，减少了煤柱损失，增加了矿井的生产效益。在设计中。为了尽可能地实现集约生产，采用一井一面的高效矿井模式。在设计中，采用了综采综掘等先进工艺和技术。这不仅提高了煤炭的开采和掘进效率，而且减小了建井工期和初期投资。运煤采用皮带运输。本矿大巷和平巷辅助运输采用矿车运输，工作面顺槽采用单轨吊辅助运输，提高运输能力大和运输连续性，使辅助运输更高效，更安全。通过不断优化设计，优化开采布局，简化生产系统，通过采用先进的技术和装备，提高了开采机械化水平，实现了高度集中生产，进而达到安全、高产、高效的目标。关键词：集中布置；倾斜长壁；带区开采；沿空掘巷AbstractThis design

3、is the new mine design of Changping No.4 mine with capability of 3.0Mt/a , and it is a high production and high efficiency mine with one production and one mining face. Changping No.4 mine lies in West of GaoPingnin ShangXi province. The traffic of road and railway is very convenience to the mine. T

4、he run of the minefield is 5.0km ,the width is about 3.8km，well farmland total area is 18.942.Through an in-depth analysis of geological data, the development of vertical shaft with single level is adopted. Main shaft, auxiliary shaft and air shaft are all located in the central part of the minefile

5、d, and central ventilation with downcast shaft and upcast shaft side by side in the central of the mine field is used. There are three coal seams in the mine field, and the spacing among them is small and the average dip of coal seam is about 6. According to the coal seams deposit conditions and min

6、e field geological structure characteristics, the rock stratum roadways are used and through the inclined drift go into the coal seams, the bottom strata is laid in the rock stratum at +410 level. Coal mining methods are the stike inclined longwall mining method. The working system “three-eight” is

7、used in the mine daily produce. The year working days is 330.In the course of design, technical and economic comparison is used in the layout of development roadway. The whole mine field is divided into four strip section and one panel. In the strip section, jumping mining and roadway driven along g

8、ob are used, and they reduce the loss of coal pillar, and increase the coal mines production benefits. In the design, In order to realize centralized production, the pattern of high-output- and high-efficiency mine with one producing shaft and one mining face are applied. During the design, the adva

9、nced technologies and techniques such as fully mechanized mining and fully mechanized tunnelling are used. It not only improve the efficiency of coal mining and tunnelling, but also reduce the construction period of coal mine and first investment. Belt transportion is used to transport the coal. The

10、 harvesters are used for auxiliary transport in the main roadway and the entry, and the overhead monorails are used for auxiliary transport in the return air inclined drift and improve transport capacity and continuity of transport, and maked auxiliary transport more efficient, safer.Though optimizi

11、ng design and development layout, simplifying production system and adopting davenced technology and equipment, mining mechanization level is improved, and highly centalized production is realized, and the goal of safty-high-output-and-high-efficiency mine is achieved.Keywords: concentrated layout;
