山脚树煤矿1.5Mta新井初步设计.doc

1、摘 要本设计包括三个部分：一般部分、专题部分和翻译部分。一般部分为山脚树煤矿1.50 Mt/a新井设计。山脚树煤矿位于贵州省六盘水市境内，红果至水城铁路干线和盘(县)水(城)公路从矿区通过，通便利。井田走向长度约5.30 km，倾向长度约3.50 km，面积约18.27。主采煤层为12煤层，平均倾角为10.5，平均厚度为3.17 m。井田工业储量为357.41 Mt，可采储量为266.36Mt，矿井服务年限为136.59 a。矿井正常涌水量为160 m3/h，最大涌水量为600m3/h。矿井相对瓦斯涌出量为50.73m3/t，属于高瓦斯矿井。根据井田地质条件，提出四个技术上可行的开拓方案。方案

2、一：双立井两水平开拓，暗斜井延伸；方案二：双斜井两水平开拓暗斜井延伸；方案三：双斜井两水平开拓暗立井延伸；方案四：双斜井三水平开拓。通过技术经济比较，最终确定方案二为最优方案。设计首采区采用采区准备方式，工作面长度210 m，采用一次采全高采煤法，沿空掘巷，矿井年工作日为300 d，工作制度为“三八制”。大巷采用胶带输送机运煤，辅助运输采用矿车运输。矿井通风方式为中央边界式。专题部分题目：煤与瓦斯共采技术现状综述，煤与瓦斯共采技术实现工作面Y型通风，根本上解决了上隅角瓦斯积聚难题，利于实现高浓度瓦斯抽采，有效解决了工作面的瓦斯超限问题，成倍提高我国高瓦斯难抽放煤层工作面的单产水平。是绿色采矿的
