1、兴隆煤矿矿井2,3号煤层初步设计摘 要本次是兴隆煤矿矿井2,3号煤层初步设计,设计图纸共七张,说明书共十章。根据采矿工程的需要和特点,设计重点为第四、六、九章,其他章节做一般的选型计算。 本井田位于陕西省韩城市北24km的马庄村西南,行政区划隶属韩城市龙门镇及盘龙乡管辖。本井田内有多层煤,本次设计为2,3号煤层,平均厚度均为3.50m。煤层有煤尘爆炸性,煤层无自燃倾向。矿井属于突出矿井,2号煤层瓦斯相对涌出量为6.04m3/t,3号煤层瓦斯相对涌出量为8.32m3/t。本矿井采用双斜井单水平开拓,采煤工艺为走向长壁综合机械化采煤,作业制度采用“四六制”。工作面的设备有双滚筒采煤机、液压支架、可
2、弯曲刮板运输机、破碎机、转载机等。采空区采用全部垮落法处理顶板。本矿井设计年产量为1.2Mt/a,采用一套综采设备来满足产量的要求。 矿井运输大巷采用胶带运输作为主运输,采用无极绳连续牵引车作为主要辅助运输,矿井通风采用轴流式扇风机,抽出式通风方式。关键词:开拓;采区;工艺;通风;保护层。1Abstract This paper mainly designs coal mining of XingLong colliery, No. 2 and 3 coal bed. There are seven design drawings altogether, and ten chapters in
