1、前言毕业设计是对大学三年所学知识的一次综合考察,是对学生综合能力的一次系统训练。本次设计的内容是阳泉市上社煤炭有限责任公司一盘区8#煤层初步设计。是在阳泉市上社煤炭有限责任公司煤矿井田概况和地质特征的基础上,结合搜集到的其它相关原始资料、运用所学知识、参考煤矿开采学、煤炭工业矿井设计规范、煤矿矿井开采设计手册等参考资料,在辅导老师深入浅出的精心指导下独立完成。在设计的过程中我受益非浅。设计包含说明书和图纸两部分。内容及结构依毕业设计大纲、毕业论文补充规定及撰写规范完成。本设计结合实际、考虑国情、贯彻国策,力求达到矿井设计的终极目标经济、合理。通过本次设计,自己各方面能力都有所提高,获益良多。但
2、自己水平仍然有限,错误疏漏之处恳请各位老师批评指正。vii摘 要本次设计是阳泉上社煤炭有限公司一盘区8#煤层,说明书共八章。根据采矿工程的需要和特点,重点设计为第二、三章,其他如井底车场、采区车场及硐室施工设计仅做一般的选型计算。阳泉市上社煤炭有限责任公司井田位于阳泉市盂县南娄镇北上社村南,县城西南12km,地处沁水煤田北部,地理坐标为北纬375844380045,东经11316571132109。该井田东西长5.5km,南北宽3km,面积12.6854km2。盂-寿公路由井田的北界通过,并与阳-盂公路相连接,可承担本矿井煤炭外运任务,另外,本矿南距石-太铁路阳泉站40km,亦可经铁路将煤炭运
3、往全国各地。煤炭交通外运条件好。 矿井采用主斜副立开拓方式,回采工艺采用综采,采煤方法采用倾斜长壁采煤法,采用“四六制”作业制度。工作面的设备有双端可调双滚筒采煤机、液压支架、可弯曲刮板运输机、破碎机、转载机等。顶板管理采用液压支架,采空区处理采用全部跨落法。矿井绝对瓦斯涌出量为30m3/min,相对瓦斯涌出量为5.9m3/t,CO2绝对涌出量为0.91m3/min,相对涌出量为1.80m3/t,属低瓦斯矿井。 井田煤层产状基本是一东西走向,向南倾伏的单斜构造,局部略有起伏,井田内地层比较平缓,倾角一般35,局部可达14。井田内尚未发现有断层、陷落柱分布。井田构造属简单。本井田划分为3个盘区,
4、本次设计为一盘区。一盘区可采煤层主要为8#煤层。8#号煤原煤灰分较低,硫分也较低。经洗选后,灰分均有较大幅度降低。经在附近煤矿采样试验,8#煤层均属于中等可选。本矿井设计一盘区的设计生产能力是120万吨,采用一套综采设备来满足产量的要求。该采区运输大巷采用皮带运输作为主运输,采用无极绳绞车作为辅助运输。采区通风采用轴流式扇风机、抽出式通风,通风方式为中央并列式。关键词:低瓦斯;主斜副立开拓; 一盘区;综采;长壁采煤法。AbstractThis design is the Yangquan Club coal limited an area 8# coal seam, manual chapte
