许疃煤矿1.8Mta新井设计.docx

1、摘 要本设计包括三个部分：一般部分、专题部分和翻译部分。一般部分为许疃煤矿2.4Mt/a新井设计。许疃矿位于安徽省宿州市西南部，地处蒙城县板桥镇某乡境内。其地理坐标为东经1164011645，北纬33213326。井田内地势平坦，北部略高于南部，海拔标高在+24.5+26.5m之间，一般为+25.5m左右。许疃井田境界为：北以 F7断层为界；南以板桥断层为界；浅部以石炭系第一层石灰岩顶界面为界；深部某断层以南以32煤层-800m水平地面投影线、某断层以北以F5断层为界。井田走向长1013km，倾斜宽37km，井田面积52.5923km2。主采煤层为7号煤，平均厚度为3米。矿井工业储量为347.

2、42Mt，可采储量为221.32Mt，设计服务年限87.83a。矿井正常涌水量为550m3/h，最大涌水量为650m3/h。矿井相对瓦斯涌出量为11m3/t，绝对瓦斯涌出量为30.806m3/min，属低高斯矿井。煤层无自然发火倾向，但煤尘有爆炸危险性。根据井田地质条件，提出四个技术上可行的开拓方案。方案一：一水平立井开拓，东翼中部开掘下山过断层开采断层以下的煤炭；方案二：一水平立井开拓，井底车场开掘下山过断层开采断层以下的煤炭；方案三：两水平立井开拓，立井直接延深；方案四：两水平立井开拓，暗斜井延深。通过粗略和详细技术经济比较，最终确定方案一为最优方案。一水平立井开拓，东翼中部开掘下山过断层

3、开采断层以下的煤炭。整个井田划分为2个带区和3个采区。考虑到井田东西走向较长，矿井采用中央并列式通风方式。矿井采用带区式准备方式，工作面设计长度230m，采用综合机械化一次采全厚采煤工艺。矿井年工作日为330d，昼夜净提升时间为16h。矿井采用“四六”制工作制度，三班生产，一班检修。生产班每班完成3个采煤循环，检修班完成1个采煤循环。循环进尺为0.8m，日产量5506.2t。矿井煤炭采用胶带输送机运输，辅助运输采用蓄电池式电机车牵引固定箱式矿车。主井采用两对12t底卸式箕斗提煤，副井采用一对1.5t矿车双层四车加宽罐笼运送物料和升降人员。专题部分题目是综采工作面矸石充填技术初探。分析矸石充填技

5、rground mine design of Xutuan Coal Mine. Xutuan Coal Mine lies in the west of Suzhou City, Anhui province. The transportation in the mining area is very convenient. Its about 13.5 km on the strike and 45 km on the dip, with the 52 km2 total area. There are 1 minable coal seam. The main aquifer coal

6、seam is 7 coal seam with an average thickness of 3 m, and the dip of 7 coal seam is 014. The proved reserves of this coal mine are 347.42 Mt and the minable reserves are 221.32 Mt, with a mine life of 87.83 a. The normal mine inflow is 550 m3/h and the maximum mine inflow is 650 m3/h. The mine relat

7、ive gas emission quantity is 10.9 m3/t, and the absolute gas emission quantity is 30.806 m3/min. Thus, it is a low gas mine. The coal seam has no spontaneous combustion tendency, but the coal dust has explosion hazard.Designed first mining district makes use of the method of the mining district prep

8、aration. The design length of working face is 230 m, which uses fully mechanized mining with top coal caving technology. The working days in one year are 330. Everyday it takes 16 hours in lifting the coal. The operation mode in the mine is “three-eight” with two teams mining and the other overhauli

9、ng. Every mining team makes three working cycle, and the overhauling team makes one working cycle. So everyday there are 7 working cycles. The advance of a working cycle is 0.8 m, and the quantity of 5506.2 ton coal is maked everyday.Main roadway makes use of belt conveyor to transport coal resource

10、, and mine car to be assistant transport. The main shaft uses two double 12 t skips to lift coal and the auxiliary shaft uses a twins wide 1.5 t four-car double-deck cage to lift material and personnel transportation.The topics of special subject parts is Working Face of waste filling technology .Th
