设计总说明 本设计包括两个部分：一般部分和专题部分。 一般部分为新井设计，全篇共分为十个部分：矿区概述及地质特征、井田境界及储量、矿井工作制度、设计生产能力及服务年限、井田开拓、准备方式—区式巷道布置、采煤方法、井下运输、矿井提升、矿井通风与安全和设计矿井主要经济技术指标。 。矿井平均走向长度约为km，平均倾斜长度约为km，面积平方公里。本井田内的可采煤层有煤、煤，厚度分别为m、m，总厚度为m。倾角平均为度，为缓倾斜中厚煤层。井田内工业储量×108t，可采储量×108t。 年设计生产能力万t/a，服务年限年。采用的开拓方式：第一水平标高-0 m。矿井采用走向长壁综合机械化采煤法。 矿井布置一个综采工作面保证全矿井的产量，长度m，煤在运输大巷的运输采用运输。矿井的通风方式采用通风。 专题部分为。 关键词：开拓方式；立井；两水平；走向长壁；综采；式；；； he Brief Introduction of the Design The design includes two parts : the general part and special subject part. The general part is a new design for lvjiatuo mine, the text is divided into 10 sections : Overview of mine and geological features, Mine realm and reserves, mine system design and production, mine exploration, mining area roadway layout, mining method, Underground transport, upgrading mine, and mine ventilation and mine safety technology major economic indicators. The lvjiatuo coalfield locates in the city of tangshan in hebei Province. The average strike length of the coalfield is 4.48 km. The inclination length of the coalfield is 3.4 km with an area of 25.86 square kilometers. There are two coal seams in this coalfield, No.7 coal seam, No.8 down coal seam . Their thickness are 3 m、m and the total thickness is 5 m. The average angle is 8 degrees, belongs to gently inclined medium thickness seam. The industrial reserve is 192 Mt, the workable reserve is 145Mt. The annual design production capacity of lvjiatuo mine is 1.5Mt/a and the service life is 69 years. Using vertical two levels of extending the deep dark mining exploitation: the first level elevation, the upper -850 m on stage; The second level elevation, vertical -1500 m high blast-caused stage. Using to longwall mine coal comprehensive mechanized. It make a fully mechanized coal face to meet the whole mine production, the coal face is 250m, the transport equipment in the main entry is conveyor of belt.The Mine ventilation mode adopted the mining district type. The special part is Research of coal and gas co-
