Essay

The dissertation is devoted to questions of a substantiation of rational parameters of mining technology near borders of tension fields for concrete mining - geological conditions of Lviv-Volynsk coal basin. As a result of theoretical and laboratory and industrial - experimental researches, the mechanism of intense fields borders forecasting in mine space is offered; estimations of intense - deformed conditions of surrounded rocks and definition of bearing ability and a placement of additional fastening in zones of replaceable geological structures. The offered technological decisions are introduced at recoming of borders of tensioned fields on three mines SHC "Lvivugol". Expected economic benefit on the average will be 181 grn/m on the length of the column.
