New Implementations of Komag Jigs for Coking and
The basic process of minerals' mechanical preparation, including coal, is a beneficiation process which has a decisive impact on quantitative-and-qualitative parameters of commercial products. At present the products of the MBE-CMT, Allmineral and Tenova companies have big market shares as regards foreign water pulsatory jigs, as well as ITG KOMAG on the local Polish market.

Dynamic Mechanical Response and Movement Evolution
2021-11-24 In the mining process of a coal seam containing a fault structure, due to the influence of mining stress, the rock mass inside the fault zone and between the fault and the coal pillar that is preserved to prevent fault activation is prone to producing damage and activation. This study is focused on this problem. Based on the analysis of the failure, activation and

2010-10-18 The mechanical anchor bolt, the oldest design in use in underground coal mines, was the main roof support used in the coal mining industry due to the rapid rate of installation. Today, the fully grouted roof bolt is considered superior to the mechanical anchor bolt because of a better anchorage capacity and load transfer capability.
