永煤陈四楼矿1.5Mta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。一般部分为陈四楼矿1.5Mt/a的新井设计。陈四楼煤矿位于河南省永城市境内，矿区北靠陇海铁路，东临京沪铁路，青（龙山) 阜（阳）铁路从矿区东南约20 km处穿过，西有京九铁路商阜段，交通十分便利。井田南北走向长平均约5.11 km，倾向长平均约3.99km，井田水平面积为18.27km2。主采煤层二2层，即2号煤层，平均倾角7，厚约6.45m。井田工业储量为172.79Mt，可采储量115.79Mt，矿井服务年限为59.4 a。井田地质条件简单。表土层平均厚度200 m；矿井正常涌水量为894m3/h，最大涌水量为1200 m3/

2、h；煤层硬度系数f=2.5；矿井绝对瓦斯涌出量为0.68 m3/min，属低瓦斯矿井；尘的爆炸性和自然发火危险性都较低。根据井田地质条件，提出四个技术上可行开拓方案。方案一：立井至450m，单水平开拓，煤层运输大巷，岩层轨道大巷；方案二：立井至450m，单水平开拓，双岩层大巷；方案三：立井至450m，单水平开拓，煤层运输上（下）山，岩层轨道上（下）山；方案四：立井至450m，单水平开拓，岩层盘区上（下）山。通过技术经济比较，最终确定方案一为最优方案。将主采煤层一个水平，水平标高-480 m。设计首采区采用带区准备方式，工作面长度178 m，采用综采放顶煤采煤法，采用全部垮落法处理采空区。矿井采

3、用“三八”制作业，日进5个循环，循环进尺0.686m，日产量4888.49 t。大巷采用带式输送机运煤，辅助运输采用1 t固定箱式矿车主井采用两个16 t侧卸式箕斗提升煤炭：副井设计采用装备一对多绳1 t矿车双层四车窄罐笼和一个1 t矿车双层四车宽罐笼带平衡锤提升设备、人员、材料和矸石。矿井采用中央并列式通风。专题部分题目是深部软岩巷道变形机理及支护技术翻译部分是一篇关于水力压裂消突数值模拟及可控压裂技术研究的论文，英文原文题目为：Numeric Analysis of Hydraulic Fracturing Technique in Preventing Outburst and the

Chen si lou coal mine lies in Yongcheng, Hen

5、an province. North of Longhai railway in mining area, East of Beijing-Shanghai Railway, Qing (Longshan ) -Fu (Yang) railway from the mine Southeast of about 20 km across, West Beijing-Kowloon Railway-Fu, the traffic is very convenient. Its about5.11 km on the strike and 3.99 km on the dip,with the 1

6、8.27 km2 total horizontal area. The minable coal seam of this mine is only 2 with an average thickness of 6.45 m and an average dip of 7. The proved reserves of this coal mine are 172.79 Mt and the minable reserves are 115.79 Mt, with a mine life of 59.4 a. Average thickness of overburden 200 m ;The

7、 geological condition of the mine is relatively simple. The normal mine inflow is 894 m3/h and the maximum mine inflow is 1200 m3/h. hardness coefficient of coal seam f=2. 5 ; Absolute for gas emission in coal mine 0.68 m 3 /min , Is a low gas mine; Dust explosive and less risk of spontaneous combus

8、tion 。Based on the geological condition of the mine, I bring forward four available project in technology. Programme a: shaft to 450m , single level develop, seam transport large Lane, rock track large lane ; programme second: shaft to 450m , single level develop, double rock large lane ; programme

9、three: shaft to 450m , single level develop, seam transport Shang (Xia) mountain, rock track Shang (Xia) mountain ; programme four: shaft to 450m , single level develop, rock disk area Shang (Xia) mountain . Through technical and economic comparison to finalize the programme for best program. Main s

Designed first mining district makes use of the method of panels in mining area, the length of working face is 178 m, which use top coal caving to exploit coal,fall to dispose worked out section. The working system is “three-eight”, with five working cycle

11、every day. Advance of working cycle is 0.7 m, and quantity of 4888.49 ton coal is maked everyday.Main roadway makes use of belt conveyor to transport coal resource, and mine car to be assistant transport. Main shaft makes use of skip to transport coal resource, when subsidiary shaft makes use of cag
