摘　　要：通过调研传统井下煤仓的布置形式、容量大小、施工方法及支护方式等基础信息,阐述8个省份19对矿井井下煤仓的布置形式及围岩特征,分析矿井产能与主井煤仓容量的匹配关系,探究煤仓高度、煤仓直径对煤仓径高比和煤仓容量的影响规律,总结传统井下煤仓的施工方法与支护方式。基于工程类比分析,给出井下大直径煤仓的设计与施工建议,确定马泰壕煤矿大直径主井煤仓的设计与施工方案。Based on the investigation of the layout form,capacity,construction method and support mode of the traditional underground coal bunker,the layout and surrounding rock characteristics of 19 pairs of underground coal bunkers in 8 provinces are described,and the matching relationship between the mine capacity and the main shaft coal bunker capacity,explore the influence of bunker height and bunker diameter on bunker diameter height ratio and bunker capacity,the construction methods and support methods of traditional underground coal bunker are summarized.Based on engineering analogy analysis,the design and construction suggestions of large diameter coal bunker are given,determine the design and construction scheme of large diameter main shaft bunker in Mataihao coal mine.
