Registration Date 12-02-2021 Organization Institute of Geotechnical Mechanics named by N. Poljakov of National Academy of Sciences of Ukraine popup.description2 The object of study – the intensity of wear of the ends of special metal cylindrical rods during their abrasion with a drilling rig on the rock. The purpose of the work – to determine the abrasiveness of rocks by the intensity of wear of special metal rods during their abrasion. Research methods – laboratory tests by a special method. As a result of the work, data on the abrasiveness of such rocks as sandstone, siltstone, argillite, mica sandstone, mica argillite, Gravel, conglomerate were obtained. The results of the conducted researches are analyzed and the corresponding conclusions and recommendations concerning the further development of the direction of work – reduction of expenses and expenses of expensive hard-alloy cutters by tunnel combines are made. Results of implementation of work – application of the received conclusions-recommendations will allow to control consumption of expensive hard-alloy cutters by tunnel combines when conducting mining works on breeds of various durability and abrasiveness that has big social and economic value, and also by means of the further researches will give the chance to reduce power expenses. both on the destruction of the rock and on the wear of the rock-destroying tool of mining machines.  Product Description popup.authors popup.nrat_date 2021-02-12 Close
