摘要
根据33042、33044巷不同区域地质条件、盖山厚度并通过分析与3304工作面相邻的3306、3305工作面留巷矿压观测报告,总结寺河矿应用高强锚索留巷以来的经验教训,进行了33042、33044巷的留巷支护设计。实际留巷效果表明,留巷取得了成功,为大采高工作面顺槽巷道留设提供了宝贵经验。
On the basis of geology condition and covering thickness in the different areas of Roadway 33042 and 33044,the pressure monitoring report in No.3305 and No.3306 working faces with high-strength cable and anchor wire was studied in order to design the support for entry retained in Sihe mine.The results showed that the design was successful and valuable for the crossheading entry on large-mining-height working faces.
