1、摘 要本设计包括三个部分：一般设计部分、专题设计部分和翻译部分。一般部分针对济三矿进行了井型为4.0 Mt/a的新井设计。济三矿位于山东西南部，南北走向长7.5 km，南北倾向宽7.0 km，面积53.0 km2。主采煤层为3#煤层，平均倾角5，平均厚度5.26 m。井田工业储量为548.08 Mt，可采储量401.43Mt，矿井服务年限为72 a。矿井正常涌水量为377m3/h，最大涌水量为516m3/h；矿井相对瓦斯涌出量为2.01 m3/t，属低瓦斯矿井。根据井田地质条件，设计采用立井单水平开拓方式，井田采用盘区式布置方式，共划分为两个盘区，辅助大巷、胶带机大巷皆为煤层大巷，布置在3#煤
2、层下方。针对东翼盘区采用了盘区准备方式，共划分14个区段工作面，并进行了运煤、通风、运料、排矸、供电系统设计。针对3101工作面进行了采煤工艺设计。该工作面煤层平均厚度为5.26m，平均倾角5，直接顶为泥岩，老顶为细砂岩。工作面采用走向长壁综采一次采全高采煤法。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，每天九个循环，循环进尺7.2m，月推进度216m。大巷采用胶带输送机运煤，辅助运输采用无轨胶轮车运输。主井采用两套带平衡锤的22t箕斗提煤，副井采用一个1.5 t矿车双层四车宽罐笼，一个1.5t矿车双层四车标准罐笼和一个带平衡锤的1.5 t矿车双层四车标准罐笼运
3、料和升降人员。专题部分题目为济三矿边角煤煤矸置换工艺研究，就目前矿井开采所产生边角煤的问题进行分析及解决方法的研究。翻译部分题目是“the 23rd International Conference on Ground Control Ming”中的Development of a statistical technique for a ssessing sandstone escarpment stability，论文主要分析煤炭资源开采过程中影响悬岩稳定性的因素以及如何保证悬岩的稳定。关键词：济三；立井单水平；综采大采高。 ABSTRACTThis design can be divide
4、d into three sections: general design, monographic study and translation of an academic paper.The general design is about a 4.00Mt/a new underground mine design of Jisan coal mine. Jisan coal mine is located in Jining, Shandong province. Its about 7.0 km on the strike and 6.5 km on the dip, with the
5、 53.0 km2 total horizontal area. The minable coal seam is 3# with an average thickness of 5.26 m and an average dip of 5. The proved reserves of this coal mine are 548.08 Mt and the minable reserves are401.43 Mt, with a mine life of 72 a. The normal mine inflow is 377 m3/h and the maximum mine inflo
6、w is516 m3/h. The mine gas emission rate is 2.01 m3/t which can be recognized as high gas mine. Based on the geological condition of the mine, this design uses a vertical shaft single-level development method ,which divided into two panel type, and auxiliary roadway, belt conveyor roadway and return
7、 airway are all mine roadways, arranged in the floor rock of 3# coal seam. Using the panel to prepare for the East Wing panel,divided into 14 sections face,and coal,ventilation,material transport,to discharge refuse,power supply system design.The design conducted coal mining technology design agains
8、t the 3101 face. The coal seam average thickness of this working face is 5.26 m and the average dip is 5, the immediate roof is mud stone and the main roof is sand stone. The working face applies fully mechanized longwall full-height coal caving method, and uses double drum shearer cutting coal whic
9、h cuts twice each working cycle. Four-six working system has been used in this design and the depth-web is 0.8 m with eight working cycles per day, and the advance of a working cycle is 7.2 m and the adv- ance is216 m per month.Main roadway makes use of belt conveyor to transport coal resource, and
10、battery ocomotive to be assistant transport.The main shaft uses double 22t skips to lift coal with a balance hammer and the auxiliary shaft uses a twins narrow 1.5 t four-car double-deck cage and a wide 1.5t four-car double-deck cage to lift material and personnel transportation.The monographic stud
