【摘要】 为寻求厚大矿体安全、高效、低耗的采矿方法 ,易门矿务局联合有关单位在凤山矿开展了“侧向挤压连续推进振动出矿崩落法”的研究工作。进行了包括室内放矿模拟试验研究、爆破漏斗试验研究、凿岩爆破参数研究、新型振动出矿底部结构与拉底扩漏工艺研究、计算机控制放矿管理研究、以及从采场结构参数到回采工艺技术等一整套采矿方法试验研究工作 ,形成了比较完善的新工艺 ,填补了我国在该领域研究的空白更多还原

【Abstract】 To seek for a safe,highly efficient and low cost mining method for thick and large ore bodies,a Yimen Mine Administration Bureau sponsored research on the caving method of side extruding continuous advancing vibratory ore drawing was carried out at Fengshan Mine.It included ore drawing simulation test,crater test,drilling blasting parameter study,research of the new bottom structure and undercut cone enlargement of ore drawing research of computer controlled drawing and a whole set of mining research from the stope structure parameters to extraction.As a result,a comparatively perfect new technology was formed,which has filled the gap in China’s research of this field.更多还原
