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。
一般部分是内蒙古伊泰酸次沟矿1200万吨井型的新井设计。其内容主要有：
1．井田概况：矿井位于内蒙古鄂尔多斯境内，地理位置优越，交通便利。井田走向长11.5km，倾斜长5.7km，主要可采煤层有4、6及6（上）煤层，煤层倾角10°左右，属低瓦斯矿井。井田地质条件比较简单。
2．开拓开采设计：根据新酸次沟矿煤层储存条件及煤炭部设计规范，确定井田采用斜井开拓，井田分为两个水平，一水平标高为+988m，二水平标高为+940m,矿井服务年限为79年。
3．采煤方法设计：设计工作面采用综采放顶煤一次采全高开采，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1200万t/a。设计工作面采用四六制工作。
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选择FBCDZ-8-№30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1.8m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。
专题部分针对酸次沟煤矿井下属于煤层自然比较严重，以及顶板管理难度大、粉尘控制困难、二氧化碳的涌出频繁等，经过实践的总结，摸清各事故的规律，针对其制定了一套科学、可靠的井下事故应急处理预案，确保煤矿安全生产。

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 1200 thousand tons of Suancigou Coal Mine in Yitai coal industry group in Inner Mongolia Province. The main is as following:
1.The general of the mine. It is located within the boundaries of Erodes County in Inner Mongolia, with ascendant geographic location and convenient transportation. The mine trend covers 11.5kilometers long and 5.7 kilometers wide. No.4、No.6 and No.6 better coal seam is the main minable one, and its dip angle is at an angle of 10 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 Suancigou Coal Mine’s coal seam and the specification for design the Ministry of Coal issued, mine is divided into two levels, one level of elevation is +988 m, elevation to the second level of +940 m and that the service life of the mine is 79-year.
3. The design for the method of coal mining. The designed coal faces fully mechanized caving mining a high-wide exploitation, 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 12 million 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. FBCDZ-8-№30master 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 1.8-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，Suancigou Coal mine for the thematic part of coal are a more serious nature of the mine, as well as the management of difficult roof, dust control difficult, frequent, such as carbon dioxide emission, after summing up the practice to find out the laws of the accident, for its development of a set of scientific and reliable underground emergency plans to deal with to ensure that the production of coal mine safety.
