1、山西大同大学煤炭工程学院18届本科生毕业设计摘 要大同煤矿集团恒宝源煤业有限公司井田位于朔州市朔城区下团堡乡上磨石沟-白家窑村一带。行政区划属朔城区下团堡乡管辖。本矿资源储为2958.59万t,设计可采储量为1936.43万t。目前开采11号煤层,开采11号煤层并达到90万t/a时的矿井最大相对瓦斯涌出量为1.13m3/t,最大绝对瓦斯涌出量为0.5m3/min,属低瓦斯矿井。11号煤层平均厚7.6m,全区可采。11号煤层厚度为7.57.7m,属可采的稳定煤层。含01层夹矸,煤层结构较简单,可采煤层总厚7.6m。直接顶板为粉砂岩或中细砂岩;底板为黑色泥岩或铝土质泥岩。本井田划分为三个,采用主、
2、副斜井开拓方式,采煤方法采用后退式、综合机械化放顶煤采煤法,采用“四六”作业制度。工作面的设备有双滚筒采煤机、液压支架、可弯曲刮板运输机、破碎机、转载机等。采空区采用全部垮落法处理顶板。本矿井设计年产量为0.9Mt,采用一套综采来满足产量的要求。矿井运输大巷采用皮带运输作为主运输,采用矿车作为辅助运输,矿井通风采用中央并列式、抽出式通风方式。关键词:瓦斯;顶板管理;综采AbstractDatong Coal Mining Group Hengbaoyuan Coal Industry Co., Ltd.
