So we have decided to alter the content structure of the magazine in that we integrated the staff news in the \u201cNews\u201d section and post-mining activities will no longer be the focal theme of one issue each year but rather will feature more generally in each of the six annual editions. In doing this we highlight the special significance of the work that is being done to manage the legacy of the mining industry. In this context the current issue discusses the employment drive under way in Germany\u2019s former coalfield regions, reports on how know-how is being transferred from the Research Center of Post-Mining &#8230; <a href=\"https:\/\/2025.mining-report.de\/english\/current-issue-1-2021\/\" class=\"shortc-button small white\">Read more<\/a>\n<p>With my best regards \/\/ Mit freundlichem Gl\u00fcckauf<br \/>\nDipl.-Ing.

The federal government\u2019s answer is the billions set aside by the law for structural support for coal regions, which was passed parallel to the energy policy realisation found in the Coal Exit Law and provides around 40 bn \u20ac in financial aid from the government until 2038.

Depending on the bulk material to be conveyed, the chutes are often subject to severe wear, which minimizes the durability of the chutes and expensive wear protection material is often replaced at very short intervals. The wear also relates to the belt conveyor downstream of the chute. If the bulk material is strongly braked when it hits the belt, the kinetic energy of the bulk material is converted into particles and belt wear. Eccentric belt loading processes caused by transfer chutes can also often be observed.<\/p>\n<p><strong>Author: <\/strong>Dipl.-Ing. Dr. mont.

But in the sector\u2019s notoriously tough, hot conditions, there are several environmental challenges to consider and overcome when choosing and administering a grease. From equipment variations, to high loads, searing temperatures and possible contamination, there is a lot to think through before seasons are considered. How far should an operator think about the seasonality of their operation? And what are the optimum timings for doing so? This article will find out.<\/p>\n<p><strong>Author:\u00a0<\/strong>Gord Susinski, Senior Technical Adviser, Petro-Canada Lubricants Inc., Mississauga, Ontario\/Canada<\/p>\n<a href=\"https:\/\/2025.mining-report.de\/english\/mining-in-the-heat\" class=\"shortc-button small white\">Read more<\/a>\n\n\t\t<div class=\"clearfix\"><\/div>\n\t\t<hr style=\"margin-top:10px; margin-bottom:10px;\" class=\"divider divider-normal\">\n\t\n<h3>The Use of Numerical Simulations in Longwall Coal Mining<\/h3>\n\n\t\t<div class=\"clearfix\"><\/div>\n\t\t<hr style=\"margin-top:10px; margin-bottom:10px;\" class=\"divider divider-normal\">\n\t\n<figure id=\"attachment_11622\" aria-describedby=\"caption-attachment-11622\" style=\"width: 1000px\" class=\"wp-caption alignnone\"><a href=\"https:\/\/2025.mining-report.de\/english\/wp-content\/uploads\/sites\/3\/2021\/02\/NumSim_03_geology_detailed_model.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-11622\" src=\"https:\/\/2025.mining-report.de\/english\/wp-content\/uploads\/sites\/3\/2021\/02\/NumSim_03_geology_detailed_model.jpg\" alt=\"\" width=\"1000\" height=\"489\" srcset=\"https:\/\/mining-report.de\/english\/wp-content\/uploads\/sites\/3\/2021\/02\/NumSim_03_geology_detailed_model.jpg 1000w, https:\/\/mining-report.de\/english\/wp-content\/uploads\/sites\/3\/2021\/02\/NumSim_03_geology_detailed_model-300x147.jpg 300w, https:\/\/mining-report.de\/english\/wp-content\/uploads\/sites\/3\/2021\/02\/NumSim_03_geology_detailed_model-768x376.jpg 768w, https:\/\/mining-report.de\/english\/wp-content\/uploads\/sites\/3\/2021\/02\/NumSim_03_geology_detailed_model-600x293.jpg 600w\" sizes=\"auto, (max-width: 1000px) 100vw, 1000px\" \/><\/a><figcaption id=\"caption-attachment-11622\" class=\"wp-caption-text\">a) Geology of the detailed model and position of the face start-up road; b) support pressure indicated by arrows, the layers are subdivided by bedding planes (black lines).

In this study numerical simulations are used to identify the necessary support pressure and the maximum distance between shield support and coal face in a target coal seam. The stress state, as well as the subsidence and the excavation damage zone in the hanging wall of a longwall panel are determined. Based on the excavation damage zone, the groundwater barrier of the target seam is analyzed.<\/p>\n<p><strong>Authors: <\/strong>Benedikt W\u00f6hrl M. Sc., Ivan Akinshin M.
