摘 要
矿井是一个复杂的动态系统，具有与其他工业不同的特点，其主要特点是地下作业，工作环境艰苦，自然条件复杂，因此通风和安全措施显得尤为重要。全局而言，各煤田所处的经济地理位置不同，煤层地质条件多种多样，开采方法也就多种多样。本次设计根据以上因素进行开拓开采设计，并选择多种开采技术进行对照比较。
设计针对新集二矿具体条件，内容包含：井田概况及地质特征、矿井开拓、通风设计、以及矿井安全技术措施。
井田概况主要包括矿区的地理、地形和交通；矿井的地理位置、井田范围；矿区的气象条件、地震烈度、电源和水源的概况；井田地质特征、煤层及煤质概况以及水文地质条件概况等。
矿井开拓分别论述了主井、副井、混合井的位置选择、采区的划分、水平的划分以及开采顺序、采区的布置及各巷道的布置等。
通风设计主要包括矿井通风系统的选择、矿井所需风量的计算及分配、矿井东、西两翼容易时期、困难时期的通风阻力计算以及对通风设备的选择等。
安全技术措施包括井下瓦斯预测和抽采、开采突出危险煤层的安全措施、粉尘防治、防火措施、防水措施以及矿井降温措施等。
专题部分主要是针对煤矿6-1突出煤层做防止煤与瓦斯突出设计。
关键词：系统   开拓   通风  

ABSTRACT
The mine is a complicated dynamic system,having remarkable different characteristics from other industry,speaking of the partial region,apart from some regions adopting open-air mining or even way opening up because the coal seam buries shallow or in the mountain,its main characteristic is working underground,bad working environment ,so the ventilating and the safety measure is of particular importance.On the whole,we have various mining methods based on the difference of economic geographical position,the various geological condition of the coal seam.The opening up and mining design proceeds according to the above factors,and the design choose various mining techniques for comparison.
The design aims at the coal mine of Xieqiao, the content  includes the general situation of the mine field and its geological characteristics, the opening up of the mine,the ventilating  design and the technological measure of the coal mine safety.
The general situation of the mine field mainly includes the geography, the topography and the traffic of the mine area; The geographical position of the mine,the range of the mine field; The meteorological condition of the mining area, the general situation of earthquake intensity, the power and the source of water; and the geological feature of the mine field、the coal seam、 the outline of the coal quality and the general situation of the  hydro geological condition , etc.
The opening up section of the coal mine discussed  separately on the choice of position of the main mine 、the auxiliary mine、the mixed mine、the  division of the level and the exploiting area and the exploiting order、the disposal of mining area and the tunnel,etc.
 The coal mine ventilation design mainly includes the choice of the ventilating system of the mine 、the calculation and the distribution of the necessary wind quantity of the mine 、the calculating of the ventilation obstruction of the whole mine and choice  of  the ventilation facilities of easy period, difficult period, etc.
The safety technique measures include the safety monitoring control system; the safety measures of preventing the gas and the exploiting of the dangerous  bursting coal seam ; the prevention and cure of the dust of the coal; the fire prevention measures; waterproof measures; the decreasing temperature measures; pit shaft frost-proof measures ; the roof management; upgrade, transportation and electricity usage safety; industrial and civil construction contradicting earthquake etc.
