1、摘 要此次设计是大同大学煤炭工程学院采矿系专升本班的毕业设计,本设计结合山西煤炭范各庄矿9号煤层的井田知识和地质资料,通过各种合理的方案,最后选择了设计符合矿井的开拓方案,采煤系统和个通风运输生产系统。此次设计为范各庄9号煤层的矿井设计,9号煤层地质构造简单,平均厚度 可达5.12m左右,煤层倾角在10度以下,为近水平煤层,瓦斯浓度低,不容易发生危险,矿山工业储量为14452万t,可采储量为10155.44万 t,设计生产能力为300万t/a,总共煤层采煤使用寿命为60年。经过多种意见的比较,最终选择了主副井都是立井的开拓方式,该煤层一共分4个带区,首采区为北1带区,首采区采用的是全部垮落法处
2、理采空区,此操作简洁快速,技术简单方便,便于操作,。矿井采用中央并列式通风的方法。关键词:立井开拓;带区式;中央式ABSTRACT This design is the graduation design of the mining Department of Datong University Coal Engineering College. This design combines the knowledge and geological data of the well field of No. 9 coal seam of Shanxi Coal Fangezhuang Mine.
3、Through various reasonable schemes, the design was finally selected. In line with the development plan themine, Coal mining system and a ventilation transportation production system.The design is a mine design for the No. 9 coal seam in Fangezhuang. The geological structure of the No. 9 coal seam is
4、 simple, the average thickness can reach about 5.12 M, and the dip angle of the coal seam is below 10 degrees. It is a near-horizontal coal seam with low gas concentration and is not prone to danger. The mine industrial reserves are 115.67715 million T. The recoverable reserves are 102.24 metric ton
5、s, the design production capacity is 10,000 t/a, and the service life is 60 years. After a variety of opinions, the main and secondary wells were finally selected as the way to open up the wells. The coal seam was divided into 6 zones. The first mining area was the North 1 zone. The first mining are
6、a used the whole collapse method to deal with the empty mining area. This operation is simple and fast. The technology is simple and convenient, easy to operate. The mine adopts a central parallel ventilation method.Key words: well development; Band type; Central style目 录1矿区简述以及井田地质构造11.1矿区简述11.1.1交
