前言本设计包括两个部分：一般部分和翻译部分。一般部分：燕子山矿120万t/a新井设计。井田东西长4.03km，南北宽3.5km，面积14.1km。主采煤层为8号煤，平均倾角为13，煤层平均总厚为5.6 m。井田地质条件较为简单。井田工业储量为12617t，矿井可采储量9395万t。t。矿井设计生产能力120万t/a,服务年限为56 a。矿井瓦斯涌出量较低，为瓦斯矿井。井田采用立井单水平开拓，水平标高为-690m。全矿采用带区布置。矿井通风方式为中央并列式通风。主要通风机的工作方法为抽出式。工作面采用“U”型通风。矿井年工作日为300 d，工作制度为“四六”制。一般部分共包括6章：1.矿区概述及井田地质特征； 2.矿井生产现状；3. 带区设计；4.采煤方法；5.矿井通风及安全；6.矿井基本技术经济指标。 翻译部分是关于煤的低温氧化模型及氧气消耗、氧化产物、反应机理及动力学模型。ABSTRACTThis design consists of three parts: the general part, the special part and translated part.The general part is a new design of Gu cheng mine, 1.2Mt/a. The N-S of the minefield is4.03 km ,the W-E is about 5.6km，the area is 14.12.The8#coal seam is the main coal seam, and its dip angle is 13 degree. The thickness of the mine is about 5.6m in all. The geological structure of this area is simple. The proved reserves of the minefield are 126.17 million tons. The recoverable reserves are 93.95million tons. The designed productive capacity is 12 million tons percent year, and the service life of the mine is 56years. The gas of the mine is low gaseous mine.The use of single-level mine shaft development, the level of elevation for-690m. With a district-wide arrangement of mine. For the central ventilation shaft ventilation tied. The working methods of the main fan for the out-type. Face the use of U-type ventilation.The working system “fore-six” is used in the yanzishan mine. It produced 300d/a.This design includes five chapters: 1.An outline of the mine field geology; 4.development engineering of coalfield; 3 The method used in coal mining and The layout of panels; 4. The ventilation of the mine; 5.The safety operation of the mine。The special subject parts of topics is The relevant prevention of coal dust. Application method for prevention and control effectively. Such as water, ventilation, etc. Personally think in actual application of water injection equipment simple effect is obvious.The translation parts is Coal oxidation at low temperatures: oxygen consumption,oxidation
