显德汪煤矿1.8Mta新井设计.doc

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。一般部分为显德汪矿1.8 Mt/a的新井设计。显德汪于邢台市西南约35km，南部与邯郸地区武安市相接。东距京广铁路褡裢车站25km，有两条主要公路邢（邢台）渡（渡口）、邢（邢台）都（都党）及通向各村的简易公路，交通极为方便。井田边界东以F1断层为界，与章村矿三、四井相邻；北部以K2及第3勘探线为界；西以煤层露头线为界；南部与邯郸矿务局郭二庄矿为邻，东西宽约4km，南北长约5km，面积约20km2。主采煤层二层，即2号煤层和9号煤层，平均倾角12，厚约9.0 m。井田工业储量为188.31Mt，可采储量140.87 Mt，矿井服务年

2、限为60.2a。井田地质条件相对简单。表土层平均厚度80 m。矿井采用全立井，主石门与阶段运输大巷、采区上、下山相结合的开拓方式，主、副井位于井田中部。设计两个生产水平，即每个煤层布置一个水平，一水平标高-160m，二水平标高-290m，回风水平标高-160m，最大开采深度-520m左右。矿井正常涌水量为120 m3/h，最大涌水量为240 m3/h；煤层硬度系数f=2.3，煤质牌号为无烟煤；矿井绝对瓦斯涌出量为1.84 m3/min，属低瓦斯矿井；煤层有自燃发火倾向，发火期36个月，煤尘具有爆炸危险性。设计首采区采用采区准备方式，工作面长度233 m，采用一次采全高采煤法，全部跨落法处理采空

3、区。矿井采用“三八”制作业，两班生产，一班检修。生产班每班3个循环，日进6个循环，循环进尺0.6 m，日产量5617.86 t。大巷采用带式输送机运煤，辅助运输采用1.5 t固定箱式矿车。主井装备一套12 t双箕斗和一套12 t单箕斗带平衡锤提煤，副井装备一对3 t矿车双层单车罐笼带平衡锤担负辅助运输任务。矿井采用中央并列式通风。通风容易时期矿井总需风量4608 m3/min，矿井通风总阻力2096 Pa，风阻0.35 Ns2/m8，等积孔2.03 m2，矿井通风容易。矿井通风困难时期矿井总风量4608 m3/min，矿井通风总阻力2746 Pa，风阻0.46 Ns2/m8，等积孔1.74 m

4、2，矿井通风中等困难。设计矿井的吨煤成本110 元/t。专题部分题目是大倾角工作面支架稳定性研究。翻译部分是一篇关于神经网络应用程序在采矿工业中的应用的的论文，英文原文题目为：Practical Neural Network Applications in the Mining Industry。关键词：立井；两水平；上下山开采；大采高；中央并列式ABSTRACTThis design can be divided into three sections: general design, monographic study and translation of an academic pape

5、r.The general design is about a 1.8 Mt/a new underground mine design of Xiandewang coal mine. Xiandewang coal mine lies in Xingtai, Hebei province. As Peitun railway run across the east part of the mining field connect to Longhai railway, the traffic is very convenient. Its about 5.23 km on the stri

6、ke and 4.18 km on the dip,with the 20.03 km2 total horizontal area. The minable coal seam of this mine is 2 with an average thickness of 5.0 m and 7 with an average thickness of 4.0 m and an average dip of 8.9. The proved reserves of this coal mine are 188.31 Mt and the minable reserves are 140.87 M

7、t, with a mine life of 60.2 a.The geological condition of the mine is relatively simple. The normal mine inflow is 120 m3/h and the maximum mine inflow is 240 m3/h. It is bituminous coal 44 with low mine gas emission rate and coal spontaneous combustion tendency, and its a coal seam liable to explos

8、ion.The first level is at -160 m, The second level is at -290 m, Designed first mining district makes use of the method of preparation in mining area, the length of working face is 233 m, which uses fully-mechanized coal mining technology, and fully caving method to deal with goaf. The working syste

9、m is “three-eight”,with two teams mining, and the other overhauling. Every mining team makes three working cycle, with six working cycle everyday. Advance of working cycle is 0.6 m, and quantity of 5617.86 ton coal is makedeveryday.Main roadway makes use of belt conveyor to transport coal resource,

10、and mine car to be assistant transport. Main shaft makes use of skip to transport coal resource, when subsidiary shaft makes use of cage to be assistant transport. In the prophase of mining the mine makes use of centralized ventilation method,when in the evening of mining the mine makes use of areas

11、 ventilation method. At the easy time of mine ventilation, the total air quantity is 4608 m3 per minute, the total mine ventilation resistance is 2096 Pa, the coefficient of resistance is 0.355 Ns2/m8, equivalent orifice is 2.03 m2. At the difficult time of mine ventilation, the total air quantity i

12、s about 4608 m3 per minute, the total mine ventilation resistance is 2746 Pa, the coefficient of resistance is 0.465 Ns2/m8, equivalent orifice is 1.74 m2. The cost of the designed mine is 110 yuan per ton.The monographic study is bolting technology of deep well drawed by MATLAB 7.1.The translated a
