1、安徽理工大学毕业设计桃园矿井田开拓及82煤零采区毕业设计摘要 淮北矿业集团桃园煤矿位于安徽省宿州市埇桥区北杨寨乡、桃园镇、祁县镇境内。北距宿州市约11km，南距蚌埠市约75km。矿井范围北界为F1断层，南部以第10勘探线为界与祁南煤矿毗邻，西界为10煤层露头线，东界至32煤层-800m水平投影线。矿井走向南北长约15km，倾向东西宽1.53.5km，面积29.45km2。井田地质构造中等，主要可采煤层有9层，属于稳定或比较稳定煤层，具备建设大型矿井的储量条件。为了合理利用煤炭资源和充分发挥投资效益，根据国家对煤炭的需求和能源发展政策，结合本井田的地质及开采技术条件，以及目前技术装备和管理水平的
2、实际情况，本矿井的设计生产能力确定为180万t年，服务年限为58.3年。井田划分为两个开采水平，第一水平为-570m，第二水平为-800m，第一水平采用上山开采，第二水平采用上山开采。主副井布置在经线3950200039502500、纬线37110003712000之间，采用立井开拓，运输、轨道大巷布置在82煤层底板中。在井田中央布置一个风井，矿井生产采用中央边界式通风系统、抽出式通风方式。矿井延伸方式为副井采用暗斜井延伸，主井采用暗斜井延伸。采煤方法为走向长壁采煤法，工作面工艺根据煤层赋存状况采用综合机械化开采。顶板管理方式采用全部垮落法处理。矿井年工作日330天，每天净提升时间为16小时。
3、采用“三八”工作制，其中两班采煤一班检修，每班工作时间为8小时。主要运输方式采用胶带机，辅助运输采用1.5t矿车。由于本矿井水文条件复杂，煤层瓦斯含量大，煤尘有爆炸危险，因此在矿井生产过程中要注意相关安全技术措施，保证矿井安全生产。关键词：立井开拓，两水平，走向长壁采煤法，综合机械化放顶煤开采1TAOYUAN COAL MINE FIELD EXPLOIT,AND 82 OF THE ZERO AREA OF GRADUATION DESIGNABSTRACT Huaibei Coal Mining Group, located in Suzhou City, Taoyuan Yongqiao
