摘要

用天然卤水对块体进行初步软化，导致金伯利岩的强度降低30- 40%，这不仅可以提高松动的生产率，而且可以对金伯利岩的矿物复合体提供阻尼作用，以提高珠宝级晶体的安全性。本文提出了一种利用刮板与组合式设备的工艺。金伯利岩阵列的准备工作是在刮板以空闲速度移动时进行的，通过松动上层，同时通过撕裂器的齿向下层提供天然盐水，使其随后软化。刮板转动后，用加长斗挖出松动岩体，运至转运点。

KIMBERLITE DEVELOPMENT TECHNOLOGY USING A SCRAPER EQUIPPED WITH COMBINED EQUIPMENT

Preliminary softening of the massif with natural brine leads to a decrease in the strength of kimberlites by 30-40 %, which allows not only to increase the productivity of loosening, but also to provide a damping effect on the mineral complex of kimberlites to increase the safety of jewelry grade crystals. The article proposes a technology using a scraper with combined equipment. The preparation of the kimberlite array for excavation is carried out when the scraper moves at idle speed by loosening the upper layer with simultaneous supply of natural brine through the teeth of the ripper into the underlying layer for its subsequent softening. After the scraper is turned, the loosened rock mass is excavated with an elongated bucket and transported to the transfer point.
