2、、采煤方法、采区巷道布置、井下运输、矿井提升、矿井通风与安全和矿井主要经济技术指标。城郊矿位于河南省永城市境内。井田南北走向平均长3.34km,东西平均宽5.09km,面积约19.67km2。井田内可采煤层为二2、三2煤,其赋存稳定,厚度平均为2.98 m和2.95 m,倾角平均8°,为缓倾斜煤层。井田内工业储量为1.517亿t,可采储量为0.9636亿t。矿井平均涌水量为180250 m3/d,井田中各煤层沼气含量一般小于0.5cm3/g,属低沼气矿井。各煤层均无煤尘爆炸危险。各煤层均属不自燃发火煤层;地温2930。城郊煤矿年设计生产能力为120万t/a,服务年限为57.36年。采
3、用立井开拓,单水平布置。工作制度为“四六”制。第一水平标高为850m。矿井采用倾斜长壁综合机械化采煤法,一次采全高。矿井布置一个综采工作面,面长220m。煤炭通过胶带输送机运输。矿井通风方式为中央并列式。专题部分:专题题目为“留小煤柱沿空掘巷技术及其可行性分析”。主要分析了沿空掘巷留小煤柱的现状,作用,存在问题及解决办法,并从受力等方面对其进行了分析。翻译部分:翻译了一篇岩石力学与采矿科技国外杂志上的论文,题目为“用有限差分方法预测由水平和倾斜煤层开采引起的沉陷问题”。关键词:立井;带区;电机车;中央并列式ABSTRACTThis design contains three parts: th
4、e general,the special subject and the translation.The general part is a new design of Chengjiao Mine in Yongcheng coal& electricity combine. The whole article is divided into ten parts:the outline of the mine, the mine field geology,the boundary and reserves, the designed productive capacity, th
5、eservice life and working area, the coal transportation,the mine lifting,the ventilation and safety, and the main economical and technological index of the mine.The ChengjiaoMine field lies inYongcheng in Henan province. The boundary of the mine field runs 5.09km from north to south and 3.34km from
6、west to east on average. The total planearea of the mine is about 19.67km2.There is only one exploring layer-number two.Its average thickness of the seam is 2.98m and its stable andflatly inclined. Its dip angle is 8 degree on average.The industry reserves of the mine field are151.7 million tons and
7、 the useable reserves are 96.36 million tons. The average inflow rate in Chengjiao mine is 180250 m3/h. It is a lower gassy mine. The coal dust doesnt have explosion hazard as well as the self-combustion tendency. The productive capacity of Chengjiao Mine is 1.2 million tons per year,and the service
8、 life is 57.36years. The work system is 4-shift with a 6-hour workday. Therere two working levels in the mine. The first development level is located at the -850m.The comprehensive mechanized longwall caving method along the dip is used in Chengjiao Mine.There is only one working face in the mine. I
9、t is comprehensive mechanized coal face.The length of the face is 220m, and the designed productive capacity of the face is 1.2 million tons per year. Coal is transported by belt conveyer and the diagonal ventilation system is used in Chengjiao.The title of special subject is “Feasibility analysis o
