1、摘 要一般部分针对鲍店煤矿进行了井型为3.0Mt/a的新井设计。鲍店煤矿位于山东兖州市邹城境内，井田走向长约7.2km，倾向长约5.06km，水平面积约35.1km2。主采煤层为3（3上、3下）煤层，平均倾角8.9，3煤平均厚度8.81m。井田工业储量为399.267Mt，可采储量276.470Mt，整个矿井服务年限为70.89a，一水平服务年限50.57a。矿井正常涌水量为100m3/h，最大涌水量为300m3/h；矿井相对瓦斯涌出量为1.5m3/t，属瓦斯矿井。根据井田地质条件，设计采用立井两水平采带区式结合开拓，一水平标高-375 m，二水平标高-500m，在井田内划分四个采区，五个带区

2、。轨道大巷、运输大巷皆为岩石大巷，布置在3煤层底板岩层中。本矿井前期采用中央并列式通风，后期采用中央分列式（边界式）通风。针对北一带区采用了带区准备方式，共划分26个分带工作面，并进行了运煤、通风、运料、排矸、供电系统设计。针对3102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6.2。工作面采用放顶煤综合机械化采煤法。采用双滚筒采煤机割煤，往返一次割两刀。采用“四六制”工作制度，截深0.8m，每个循环进尺1.6m，每天三个循环，月推进度132m。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。主井采用两套带平衡锤的12t箕斗提煤，副井采用一对1.5t

3、矿车双层四车窄罐笼和一个带平衡锤的1.5t矿车双层四车宽罐笼运料和升降人员。专题部分题目为深部高温矿井热害治理技术研究，详细阐述了国内外对于矿井热害理论、技术的研究现状，并针对现有理论不足，对井巷喷注隔热材料新型井下主动降温方法作了初步实验探究。翻译部分题目为Modeling and Simulation of the Underground Mining Transportation System，主要介绍了系统仿真在大型地下煤矿运输系统优化模型中的应用情况。关键词：鲍店煤矿；立井两水平；采带区布置；放顶煤；中央并列式；深井热害 ABSTRACTThe general part of the

4、 design is about a 3.0 Mt/a new underground mine design of Baodian coal mine. Baodian coal mine is located in Zouchen, Shangdong province. Its about 7.2 km on the strike and 5.06 km on the dip, with the 35.1 km2 total horizontal area. The minable coal seam is 3(3up、3down) with an average thickness o

5、f 8.81 m and an average dip of 8.9. The proved reserves of this coal mine are 399.267Mt and the minable reserves are 276.470 Mt, with a mine life of 70.89a and the first level life 50.57a. The normal mine inflow is 100m3/h and the maximum mine inflow is 300 m3/h. The mine gas emission rate is 1.5 m3

6、/t which can be recognized as gas mine. Based on the geological condition of the mine, this design uses a duel-vertical shaft two-level development method with combination of bands and districts style. The first level of elevation is located on -375 m, the second level of elevation is located on -50

7、0m, divided into four districts and five bands, and track roadway, belt conveyor roadway and return airway are all rock roadways, arranged in the floor rock of 3 coal seam. The pre method use central parallel ventilation and the post-mine ventilation is central-past ventilation (boundary type). The

8、design applies strip preparation against the first band of North One which divided into 26 stirps totally, and conducted coal conveyance, ventilation, gangue conveyance and electricity designing.The design conducted coal mining technology design against the 3102 face. The coal seam average thickness

9、 of this working face is 8.5 m and the average dip is 6.2. The working face applies top coal caving, and uses double drum shearer cutting coal which cuts twice each working cycle. Four-Six working system has been used in this design and the depth-web is 0.8 m, a working cycle is 1.6 m with three wor

10、king cycles per day, and the advance of and the advance is 132 m per month.Main roadway makes use of belt conveyor to transport coal resource, and battery locomotive to be assistant transport. The main shaft uses double 12 t skips to lift coal with a balance hammer and the auxiliary shaft uses a twi

11、ns narrow1.5 t four-car double-deck cage and a wide 1.5t four-car double-deck cage to lift material and personnel transportation.The thematic segment entitled Treatment Technologies for deep high-temperature mine heat damage, elaborating the research status quo at home and abroad to mine heat damage

12、 theory, technology, and based on lack of existing theory, a preliminary experiment to explore about new active cooling with insulation materials injection to underground roadway was conducted. The title of the translated academic paper is “Modeling and Simulation of the Underground Mining Transport
