花园煤矿0.9Mta新井设计.doc

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。一般部分为花园煤矿0.9Mt/a新井设计。花园煤矿位于山东省金乡县境内,交通便利。井田走向(南北)长度最大约为5.4km,最小约为3.4km,倾斜(东西)长度最大约为2.9km,最小约为1.8km,总面积为13.97km2。主采煤层为15煤,煤层倾角为616,平均总厚度为4.04m。井田地质条件较为简单。井田工业储量为78.371Mt,可采储量为51.53Mt。矿井设计生产能力为0.9Mt/a。矿井服务年限为44.04a,涌水量不大,矿井正常涌水量为86m3/h,最大涌水量为99.7m3/h。矿井瓦斯相对涌出量为1.732 m3/t,绝对

2、涌出量为6.866m3/min,为低瓦斯矿井。井田开拓方式为立井单水平开拓。采用胶带输送机运煤,采用矿车进行辅助运输。矿井通风方式为中央并列式通风。矿井年工作日为330d,工作制度为“三八”制。一般部分共包括10章:1、矿区概述与井田地质特征;2、井田境界和储量;3、矿井工作制度、设计生产能力及服务年限;4、井田开拓;5、准备方式带区巷道布置;6、采煤方法;7、井下运输;8、矿井提升;9、矿井通风与安全;10、设计矿井基本技术经济指标。专题部分题目是跨采巷道围岩变形规律与支护技术分析,主要分析了跨采巷道围岩变形的影响因素和变形规律,并从引起跨采巷道变形的因素的角度,分析了近年来的跨采巷道的支护

3、理论及技术,从工程实例分析了注浆加固对跨采巷道支护效果。 翻译部分主要内容关于高温度燃料电池处理煤矿低浓度瓦斯,英文题目为:Processing of coal mine gas with low methane concentrations for use in high-temperature fuel cells。关键词:立井;单水平;带区;中央并列式;一次采全高ABSTRACTThis design includes three parts: the general part, the special subject part and the translation part.Gene

4、ral part is the Huanyuan 0.9 Mt/a new coal mine well design. huayuan mine is located in counties of jinxiang in shandong province. It is very convenient to get to the mine in terms of both highway and railway. The maximum length of the coalfield is 5.4 km,and the minimum length of the coalfield is3.

5、4 km , The maximum width of the coalfield is 2.9km,and the minimum length of the coalfield is 1.8 km ,and the total area is 13.97km2.The third are the main coal seams, and its dip angle is 616 degree. The thickness of the mine is about4.04m in all. The geologic structure of this coalfield is simple.

6、The recoverable reserves of the coalfield are 78.371 million tons,and the minable reserves are 51.53 million tons. The designed productive capacity is 0.9 million tons percent year, and the service life of the mine is 44.04 years. The normal flow of the mine is 86m3 per hour and the max flow of the

7、mine is 99.7 m3 per hour. The relative mine gas gush is 1.732 m3/t and the absolute gush is 6.866 m3/min, so it is a low gas mine. The mine is a double levels to develop. The central laneway uses Belt Conveyor to transit coal, and trolley wagons are used for accessorial transportation in the roadway

8、 . The prophase ventilation mode of this mine is center juxtapose form, and the late ventilation mode of this mine is diagonal form. The “three-eight” working system is used in the huayuan mine. It produces for 330 days a year.The deneral design includes ten chapters: 1.An outline of the mine field

9、geology; 2.Boundary and the reserves of mine; 3.The service life and working system of mine; 4.development engineering of coalfield; 5.The layout of panels; 6. The method used in coal mining; 7. Underground transportation of the mine; 8.The lifting of the mine; 9. The ventilation and the safety oper

10、ation of the mine; 10.The basic economic and technical norms of the designed mine.The topic of special subject part is cross mining drift wallrock deformation regularity and supporting technical analysis, the paper analyzes the across adopt drift wallrock deformation and the factors affecting the de

11、formation regularity, and from across the roadway deformation caused by mining, analyses the factors in recent years in the cross of roadway supporting theory and technology, from engineering example analyzed the grunting reinforcement to cross mining roadway effect.Translation part is a boat Proces

12、sing of coal mine gas with low methane concentrations for use in high-temperature fuel cells. The English title is “Processing of coal mine gas with low methane concentrations for use in high-temperature fuel cells”.Keywords: Shaft; Single level; Panel; Center juxtapose ventilation; full-seam mining
