副立井暗式井口房设计与实践

Design and Practice on Underground Heapstead of Vertical Auxiliary Shaft

副井井口房是矿井诸多地面构筑物设计中的重点设防类建筑,按井筒形式分为副斜井井口房和副立井井口房。以河南大峪沟煤业集团有限责任公司新副立井井口房工程为例,结合具体的现场地质条件,对传统大开挖式和暗式平硐式设计方案进行了比较,提出暗式平硐式井口房在经济、环保及征地各方面的优势。同时从设计尺寸、施工工序、支护方案、材料配备方面提出了该矿井副井暗式平硐式井口房的设计方案,并取得了良好的应用效果。

Auxiliary shaft heapstead is an important protective construction of ground structures and it can be classified into slant auxil- iary shaft heapstead and vertical auxiliary shaft heapstead on the basis of shaft shape. This article takes the vertical auxiliary shaft heap- stead project in Henan Dayugou Coal Limited Liability Company for example, takes spot specific geologic feature into consideration, compares traditional excavation project with underground adit project. And it was concluded that underground adit project has advantage over traditional excavation project in economy, environmental protection and land acquisition. This article also put forward the design project of underground adit heapstead in design measurement, construction process, supporting design, material equipping, and this de- sign project has achieved good application effects.
