1、摘 要本设计是赵庄五矿2.4Mt/a新井设计，设计矿井为一井一面的高产高效矿井。赵庄五矿位于山西省高平市西面，交通便利。井田走向长度约4.0km，倾向长读约4.42km，井田总面积为15.4km2。通过对地质资料的深入分析，采用立井多水平开拓方案。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8左右。根据煤层赋存条件和井田地质构造特点，采用煤层大巷布置，每个煤层都布置三条大巷，井底车场位于最下煤层的底板岩层中。采煤方法采用一次采全高采煤法。矿井年工作日为330d，工作制度为“四六”制。在设计中，对大巷的布置方式进行了技术经济比较。全矿分为四个盘区。
2、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。全矿采用无极绳绞车辅助运输，个别地方用矿车，减少了换装环节，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：煤层巷道；一次采全高；盘区开采；辅助运输。 AbstractThis design is the new mine design of Zhao
3、zhuang No.5 mine with capability of 2.4Mt/a , and it is a high production and high efficiency mine with one production and one mining face. Zhaozhuang No.5 mine lies in West of GaoPingnin ShanXi province. The traffic of road and railway is very convenience to the mine.The run of the minefield is 4.0
4、 km ,the width is about 4.42 km，well farmland total area is 15.42.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 minefiled, and central ventilation w
5、ith downcast shaft and upcast shaft side by side in the central of the mine field is used. There are two coal seams in the mine field, and the spacing among them is small and the average dip of coal seam is about 3.4 . According to the coal seams deposit conditions and mine field geological structur
6、e characteristics, the coal seam roadways are used and layout of each seam is three roadways, the bottom strata is laid in the rock stratum under the coal seam floor. Coal mining methods are the stike inclined longwall mining method. In design, roadway layout of the techno-economic comparison. Mine
7、is divided into four districts. Band with skip-mining along goaf and reduces the loss of coal pillars, increasing the production efficiency of mine. In the design. Intensive production in order to achieve as much as possible, using a pattern of mine. The working system “three-eight” is used in the S
8、ehe mine. It produced 330d/a.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. In the strip section,jumping mining and roadway driven along gob are used,and they reduce the loss of coal pi
9、llar,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 advanced technologies and techniques such as fully mech
10、anized 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 monorails are used in the whole mine for auxiliary tr
