大埋深综放工作面过大陷落柱的技术与实践

Technology and Practice of Excessive Collapse Column in Large Embedded Depth Fully Mechanized Caving Face

陷落柱的出现对工作面的防治水和顶板管理带来较大影响,给安全生产带来较大困难,一般较大范围的陷落柱的出现,工作面都进行系统改造。而田陈煤矿3下7112工作面在回采过程中遇到90m×66m的大陷落柱,通过劳动组织的优化、生产现场措施的超前管控、隐患的超前防范等,不仅安全、成功、快速推过了陷落柱(历时40天),为以后遇到类似大范围的陷落柱的推采积累了宝贵的现场经验和技术参数。

The emergence of collapse column brings greater impact to the water prevention and control and the roof management of mining face, and brings greater difficulties to the safety in production. Generally, if there is a larger range of collapse column, the mining face needs systematic transformation. In the mining process of 3 下 7112 mining face of Tianhen coal mine, it encountered 90m × 66m large collapse column. By optimization of the labor organization, pre-control of production site measures, pre-prevention of hazards, it not only safely and successfully and fast pushes through the collapse column （last 40 days）, which provides field experience and technical parameters for the advancing and mining of similar large-scale collapse column.
