赵庄一矿1.20Mta新井设计.doc

1、摘要本设计是赵庄一矿1.20Mt/a新井设计。井田内有两层煤，煤层平均倾角14度。该井田煤工业储量202.08 Mt，可采储量129.57 Mt，设计服务年限为77.1年。通过对地质资料的深入分析和方案的比较，确定采用立井开拓。主井和副井位于井田储量中心处,该矿井采用中央边界式通风。全矿井设置两个开采水平，开拓方式为立井多水平上山开拓,采煤方法采用走向长臂采煤法。根据煤层的赋存情况 ，采用集中大巷的布置方式，两条大巷布置在最下煤层中。主井采用箕斗提升，副井采用罐笼提升，运煤采用皮带运输，实现了全矿井的连续运输。工作面采用国内外先进采煤设备，有利于工作面高产高效。在设计中，开拓方式、井筒位置的选

2、择、大巷布置都进行了方案比较。全矿划分为四个采区，采区采用后退式开采，减少了矿山压力，提高了安全性。设计中采用综采综掘等先进工艺和技术，提高了煤炭的开采和掘进效率，减少了建井工期和初期投资。设计矿井为一井一面的高效矿井，实了集中生产。为了优化设计，在开拓布局上进行了优化，使生产系统尽量简化。通过选用先进的技术和装备，提高开采机械化水平，实现高度集中生产，使得矿井达到高产高效的目标。关键词：集中布置；高产高效；皮带运输ABSTRACTThis design is the new mine design of Zhaozhuang 1 mine with capability of 1.20Mt/

3、a. There are two coal seams in the mine field, and the average dip angle of coal seams is 14 degree. The coal industry reserves run 202.08 Mt, recoverable reserves 129.57 Mt, design and service period is 77.1 years.After fully analyzing the geological material and technical and economic comparison,

4、vertical shaft development is used . Main shaft and auxiliary shaft is located in the laohutai mine field at the center of the reserves, is located in the shallow boundary and the eastern boundary laohutai mine field. The ventilation style is central and border ventilation method . There are two lev

5、el in the mine, explore ways of vertical single level the mountain development.Coal mining methods is strike longwall mining method.According to the modes of occurrence of coal seam, the concentration of roadway arrangement, two roadway arrangement in the lower coal. Skip hoisting is used in main sh

6、aft and cage hoisting is used in auxiliary shaft, and belt is used for coal transportation , and whole mine continuous is realized. Advanced mining equipments are used in coal mining face, which make mining face high production and high effciency.In the course of design, technical comparison is used

7、 in development style, selection of shafts position, layout of roadway. The whole mine field is divided into 4 mining sections, and in each mining section retreating mining is used. So underground pressure is reduced and safety improved. During the design, the advanced technologies and techniques su

8、ch as fully mechanized mining and fully mechanized tunnelling are used. It not only improve the efficiency of coal mining and tunnelling, but also reduced the construction period of coal mine and first cost. In design, the pattern of high-output and high-efficiency mine with one one producing shaft

9、and one mining face is applied, and centralized production is realized .To optimize the design, it has simplified the design of development layout and the production system. Through adopting advanced technology and equipment, mining mechanization level is improved ,and highly centralized production

10、is realized, and the goal of high-output and high-efficiency mine is achieved.Keywords: concentrated layout; high-output and high-efficiency; belt transport 目录前言11 矿区概况及井田地质特征21.1 矿区概况21.1.1 矿区地理位置21.1.2 矿区地形、地貌及交通运输31.1.3 气候条件及地震情况31.1.4 电源、水源及建筑材料来源31.2 井田及其附近的地质特征31.2.1 井田地质构造31.2.2 井田水文地质特征31.3
