摘要

改进用于提取钾盐的室内采矿系统目前非常重要，因为它可以解决许多任务-从提高采矿作业的安全性到提高提取矿石的质量。在工作煤层的折叠轴方向上使用生产采场，可以通过最大限度地减少对上覆煤层岩盐的修剪，从而减少矿石的稀释。通过增加生产采场的长度和采场与抽采巷道之间的平滑连接来提高联合系统的生产率。本文介绍了改进后的开发系统在乌拉尔矿业股份有限公司BKPRU-4矿区西北四五盘西四区块的应用情况。

APPLICATION OF A DEVELOPMENT SYSTEM WITH A DIAGONAL ARRANGEMENT OF PRODUCING STOPES IN THE POTASH ORE EXTRACTION

The improvement of the room mining system for the extraction of potash salts is cur-rently very relevant, as it allows solving a number of tasks – from improving the safety of min-ing operations to improving the quality of the extracted ore. The use of producing stopes ori-ented in the direction of the fold axes of the working seams allows reducing the dilution of ore by minimizing the cases of pruning of the rock salt overlying seams, as well as increase the productivity of combine systems by increasing the length of the producing stopes and a smooth-er junction of the stopes and the extraction drift. The article considers the application of an im-proved development system on the 4th western block of the 4th-5th north-western panel of the BKPRU-4 mine take of Uralkali PJSC.
