顺和煤矿采区煤仓设计及施工实践

为了形成高效的采区煤流系统，结合顺和煤矿采区巷道布置及围岩结构特征，提出两种煤流转载方案，并通过方案比选确定采用施工采区煤仓进行煤流转载的方案。针对煤仓上口为机轨合一巷道、下口为带式输送机的问题，提出采取“工字钢+钢轨+钢板”联锁支护方式以保证封口强度，以及在下口装载硐室使用“锚索+工字钢+锚喷”支护代替帮部混凝土浇筑支护，同时使用装配式模板一体式预埋浇筑的支护方式。现场应用实践表明采区煤仓的使用确保了采区煤炭的高效运输，其施工工艺可为类似条件下的煤仓施工提供参考。

Design and Practice of?Panel Bin?in?ShunHe Coal Mine

To from an efficient coal transport system, we proposed two methods of coal transport taken into account the roadway layout and surrounding strata condition of Shunhe Mine. Comparisons between the two methods indicated that using the vertical bin for the coal transfer was better than using conveyor. Considering the combined use of rail and belt transport system at the top of bin and the belt conveyor at the bottom of the bin, we proposed using “I-beam + steel rail + steel plate” to form an interlocking support pattern so as to ensure the strength at the bin opening. At the bin bottom where there was a loading chamber, an integrated support patterns using “cable + I-beam + anchoring and shotcreting” was adopted, meanwhile, one-piece precast casting support was used as well. Field application demonstrated the bin had guaranteed the efficient transport of coal from the panel, the design of the bin and its support system could provide reference for bin construction with similar condition.
