Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

The state of mining in Artemevsk Mine is analyzed, and the current and recommendable support designs are described. In unstable rock mass, it is possible to replace heavy and laborious steel frame support by less expensive and lower labor-intensive shotcrete lining with surface reinforcement without reduction in load-bearing capacity of the support. The variants of arrangement of shotcrete production plant are discussed, and the economic efficiency of the proposed wet-mix shotcreting is calculated in terms of Artemevsk Mine.
