1、摘 要本设计包括三个部分：一般部分、专题部分和翻译部分。一般部分为姚桥矿井4.0Mt/a新井初步设计，共分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、设计生产能力及服务年限；4.井田开拓；5.准备方式采区巷道布置；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。一般部分针对徐州姚桥煤矿矿井进行了井型为4.0Mt/a的新井设计。姚桥矿井位于江苏省徐州市境内，井田走向长约9.08km，倾向长约4.08km，面积约37.05 km2。主采煤层为7号煤层，平均倾角11，平均厚度8.5m。井田工业储量为502.43Mt，可采储量

2、358.20Mt，矿井服务年限为64a。矿井正常涌水量为325m3/h，最大涌水量为465m3/h；瓦斯相对涌出量远远小于10 m3/t，属低瓦斯矿井。根据井田地质条件，设计采用立井两水平开拓方式，二水平暗斜井延伸，井田采用采区式上山布置方式，共划分为5个采区，轨道大巷、运输大巷皆为岩石大巷，布置在7号煤层底板岩层中。本矿井为低瓦斯矿井，矿井通风方式采用中央并列式通风。 针对东三采区采用了采区准备方式，共划分16个分采工作面，并进行了运煤、通风、运料、排矸、供电系统设计。针对7301工作面进行了采煤工艺设计。该工作面煤层平均厚度为8.5m，平均倾角11。工作面采用综采放顶煤采煤法。采用双滚筒采

3、煤机割煤，往返一次割两刀。采用“三八制”工作制度，截深0.8m，每天六个循环，循环进尺4.8m，月推进度144m。大巷采用胶带输送机运煤，辅助运输采用蓄电池式电机车牵引固定箱式矿车。主井采用两个32t异侧装卸式箕斗提升煤炭：副井设计采用装备一对多绳1.5t矿车双层四车罐笼和一个材料宽罐笼带平衡锤提升设备、人员、材料和矸石。专题部分题目是综采放顶煤回采巷道支护技术。翻译部分题目为The rock-burst comprehensive prevention and control technology nearby Coal terminal line关键词：姚桥矿井；立井；采区布置；综采放顶煤

4、；中央并列式； ABSTRACTThis design includes of three parts: the general part, special subject part and translated part.The general part is a new preliminary design of Yaoqiao wells that annual output is 4.0Mt . The design includes ten chapters: 1. Mine and mine geological features outlined; 2. Waida realm

5、and reserves; 3. Mine system, design capacity and length of service; 4. Waida develop ; 5. to prepare the way - with the district roadway layout; 6. mining methods; 7. underground transport; 8. mine hoist; 9. mine ventilation and security technologies; 10. mine the basic technical and economic indic

6、ators.The general design is about a 4.0 Mt/a new underground mine design of Yaoqiao coal mine. Yaoqiao coal mine is located in xuzhou, jiangsu province. Its about 9.08km on the strike and 4.08 km on the dip, with the 37.05 km2 total horizontal area. The minable coal seam is 7# with an average thickn

7、ess of 8.5 m and an average dip of 11. The proved reserves of this coal mine are 502.43 Mt and the minable reserves are 358.20 Mt, with a mine life of 64.0a. The normal mine inflow is 325 m3/h and the maximum mine inflow is 465 m3/h. gas relative emission in far less than 10 m3 / t, is a low-gas coa

8、l mine.According to Ida geological conditions, the design uses a vertical shaft two horizontal development, the second level of the dark inclined shaft extension, Ida mining area up the mountain-layout is divided into five mining area ,two mining areas, track roadway, transportation roadway are rock

9、roadway layout in the coal seam floor strata. The mine for the low gas mine, mine ventilation mode with a central parallel ventilation.Using the mining area to prepare the way for East Third District was divided into 16 mining face, and coal, ventilation, material transport, to discharge refuse, pow

10、er supply system design.The design conducted coal mining technology design against the 7301 face. The coal seam average thickness of this working face is 8.5 m and the average dip is 11, the immediate roof is mud stone and the main roof is sand stone. The working face applies fully mechanized longwa

11、ll full-height coal caving method, and uses double drum shearer cutting coal which cuts twice each working cycle. Three-Eight working system has been used in this design and the depth-web is 0.8 m with six working cycles per day, and the advance of a working cycle is 4.8 m and the advance is 144 m p

12、er month.Roadway using a belt conveyor to transport coal, auxiliary transport Battery Locomotive traction fixed box-type tramcar. The main shaft with two 32t opposite side handling skip hoisting coal: the auxiliary shaft design uses a wide cage of the equipment-to-many rope 1.5t tramcar two-tier car

13、 cage and a material with a balance weight lifting equipment, personnel, materials, and waste rock.The thematic segment entitled Fully mechanized top coal seam with technologyThe title of the translated academic paper is The rock-burst comprehensive prevention and control technology nearby Coal term
