综放工作面钢丝绳锚网收尾技术研究

Study on Ending Technique of Bolting with Steel-string Meshes in Fully-mechanized Top-coal Caving Workface

针对王庄矿综放工作面底层收尾技术特点 ,在考虑收尾停采位置如何避开周期来压影响 ,增加顶煤顶板在收尾及设备回撤期间稳定性的同时 ,又考虑如何尽量缩短不放煤推进距离 ,最大限度地减少煤炭资源损失。在 432 5综放工作面收尾中设计并试验使用废旧钢丝绳 +钢网支护 ,辅之以锚索补强联合支护新工艺 ,实现收尾和设备搬迁的科学合理、快速安全、经济高效。

Based on feature of ending technique in fully-mechanized of Wangzhuang coal mine,how to avoid periodic pressure in ending stop-mining site and increase stabilization of roof in ending and install with drawed,and how to shorten propelling distance in No-placing coal,loss of coal source is reduced into maximum limit.In 4325 ending of fully-mechanized top-coal caving.Test uses combined support with waste steel-string,steel-net,and cable anchor,this craff is scientific,quick and safe,economic.
