摘要
为解决下石节煤矿214煤仓装载硐室底板遇水强烈膨胀而多次失稳破坏的难题,设计了新型壁挂式煤仓。该煤仓采用工字钢托梁、工字钢仓体托架及其固定锚索、自锁承重锚索等构建煤仓自承载系统,利用煤仓围岩承担煤仓的全部重量,去掉了煤仓下口给煤硐室承载结构。同时,采用了电渣压力焊、高强抗冲击耐磨材料等先进工艺和新材料,提高了壁挂式煤仓整体工艺水平,缩短了煤仓的建设时间,减少了给煤硐室的建设与维护费用。现场实践表明,新型煤仓稳定可靠,技术经济效益良好,在类似的地质条件下具有很好的推广应用价值。
Aiming at the intense expansion of coal feeding chamber floor for 214 coal bunker affected by water in Xiashijie Coal Mine, the wall-mounted bunker was designed. The self-bearing system of wall-mounted bunker that was composed by I-beam joists, steel joist bracket of bunker body with fixed anchors and self-locking bearing anchors, bearing the full weight of coal bunker on the surrounding rock and dislodging the beating structure at the bottom of coal feeding chamber. While using electroslag pressure welding, high-strength impact resistant materials and other advanced technology and new materials, the overall process of bunker wall-mounted was improved, the construction time of bunker was shorten, and the cost of construction and maintenance for coal feeding chamber also was reduced. Field test proved the reliability, obviously technical and economical benefits.
