桑树坪煤矿1.2Mta新井设计.docx

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。一般部分为桑树坪煤矿1.20 Mt/a新井设计。桑树坪煤矿位于陕西省韩城市境内，从下峪口至桑树坪的铁路运煤专线与西候线接轨，交通便利。井田走向长度约7.01 km，倾向长度约2.36 km，面积约14.82 km2。主采煤层为3号煤层，平均倾角为6，平均厚度为6.3 m。井田工业储量为387.84 Mt，可采储量为273.52Mt，矿井服务年限为58 a。矿井正常涌水量为532 m3/h，最大涌水量为589.7m3/h。矿井相对瓦斯涌出量为17.1m3/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。方案一：双斜井中央

2、并列式通风；方案二：双立井石门风井通风；方案三：双斜井两翼对角式通风；方案四：双立井两翼对角式通风。通过技术经济比较，最终确定方案一为最优方案。设计首采区采用带区准备方式，工作面长度210 m，采用大采高采煤法，沿空掘巷，矿井年工作日为300 d，工作制度为“四六制”。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并列式。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。是绿色采矿的发展方向，在技术上和经济上具有很大的
