摘  要

本设计包括三个部分，即矿井新井设计部分(一般部分)、专题部分和翻译部分。
一般部分是山西阳煤集团新元矿120万吨井型的新井设计。其内容主要有：
1．井田概况：矿井位于山西省寿阳县境内，地理位置优越，交通便利。井田走向长5.5km，倾斜长3.7km，主要可采煤层有15号煤层，煤层倾角6°左右，属高瓦斯矿井。井田地质条件比较简单。
2．开拓开采设计：根据新元矿煤层储存条件及煤炭部设计规范，确定井田采用双立井开拓，水平标高为+670m，矿井服务年限为56年。
3．采煤方法设计：设计工作面采用倾斜长壁采煤法，采用综采采煤工艺,一次采全高，采空区用全部垮落法处理。由一个工作面达到设计产量，工作面生产能力为120.2万t/a。设计工作面采用三八制工作。
4．矿井通风设计：根据本矿开拓开采条件，采用中央边界式通风，风量分配由内向外计算，工作面采用“U”型通风方式。掘进面用局扇进行压入式通风。根据通风容易、困难时期的通风阻力BDNo24型轴流式风机。矿井通过风机反转反风。
5．井下运输与提升：运煤采用1.2m强力皮带，辅助运输统一采用无轨胶轮车运输方式。主井采用钢丝绳强力皮带提煤，副井采用无轨胶轮车辅助运输。
6．矿井其他安全技术措施的设计：主要包括防水、瓦斯、煤尘等方面的内容。
专题部分针对新元煤矿属高瓦斯矿井，煤层埋藏深，矿井瓦斯涌出量大，严重影响矿井的安全生产。摸清新元矿瓦斯涌出规律，并制定出一套科学、可靠的瓦斯防治技术，提高矿井瓦斯防治技术水平，确保矿井安全生产。

ABSTRACT
The paper consists of three parts, namely the design of a new mine (the general part), the special part and the part of translation.
The general part is about designing a new mine with production capacity of 1800 thousand tons of Xinyuan Coal Mine in YANGQUAN COAL INDUSTRY GROUP in Shanxi Province. The main is as following:
1． The general of the mine. It is located within the boundaries of Shouyang County in Shanxi Province, with ascendant geographic location and convenient transportation. The mine trend covers 5.5 kilometers long and 3.7kilometers wide. No.15 coal seam is the main minable one, and its dip angle is at an angle of 6 or so, belonging to the type of high density of gas. It has comparatively simple geological conditions.
2． The design for opening up and mining. According to the storage conditions of Xinyuan Coal Mine’s coal seam and the specification for design the Ministry of Coal issued, it is decided that it adopts inclined shaft and vertical shaft to open up the mine, with +670m above level, and that the service life of the mine is 56-year.
3． The design for the method of coal mining. The designed coal faces are adopted long wall mining method along dip and totally mechanized coal mining technique, and to deal with the empty it is used the method of the whole caving in. At a coal face it can reach the planned yield and the average production capacity of the coal faces can reach up to 1200 thousand tons per year. It is used four-shift system.
4． The design for ventilation. In accordance with the conditions of opening up and mining, it is appropriate to adopt divisional ventilation, and the distribution of the wind is computed from the inside to the outside. The coal faces are used “W” type to ventilate. Partial blowers are used for ventilation by high pressure on the stub entry. BDNo24master blowers are suitable for the ventilating resistance of both easy and hard ventilating times. Blowers’ reversal can realize reversal ventilation in the mine.
5． Underground haulage and hoisting. It makes use of 1.2-meter-wide high-power rubber belt to transport coal, and uniformly uses trackless conveyors with rubber wheels as aided-transportation. It uses wire ropes and high-power rubber belts to hoist coal in main shaft, while trackless vehicles with rubber wheels as aided-transportation in auxiliary shaft.
6． The design for other safe techniques in mine. It mainly comprises anti-water, anti-gas, anti-coal dust and so on.
The special part refers to that, Xinyuan Coal Mine is a high-gas mine with a mass of gas emission and its coal seam is very deep, which severely affect the safe production of the mine. Because of the great seam gas content and release on the drifting faces, the over limit gas accidents occur easily in the process of breaking through roadways. To analysis the reason why gas accidents occur in
high gas outburst mines during breaking through roadways, is significant for making efficient safety measures and avoiding gas accidents. I suggest some views on the integrative control over the gas in the galleries of high-gas mines theoretically. It need to find out the regularity of gas emission in Xinyuan Coal Mine and formulate a suit of scientific and reliable technology of gas prevention and cure to heighten the technical level of gas prevention and cure in mine and insure its safe production.
