The method is based on the use of the intact rock mass stiffness matrix formed prior to mining. Modeling of the cavity growth and joint deformation of the lining and rock mass surrounding the excavation opening is performed using iterative procedures of the methods of initial stresses and initial strains. An appropriate algorithm and software complex for calculating loads on the lining of mined-out area have been developed.","PeriodicalId":196311,"journal":{"name":"Фундаментальные и прикладные вопросы горных наук","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127842656","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Высокие значения температуры регистрируются на боковых поверхностях отверстия, что указывает на значительные деформации этих участков.

Определению и сравнительному анализу коэффициентов хрупкости горных пород посвящены работы отечественных [1 – 3] и зарубежных ученых [4, 5]. В них же можно найти и обзоры предшественников по этой теме. Базируясь на известных значениях модуля упругости Е и модуля спада M, Тарасовым Б. Г. [5] проведена классификация степени хрупкости пород по коэффициентам хрупкости k1 = (M – E) / M и k2 = E/M (Е — модуль упругости, М — модуль спада), причем некоторый диапазон значений коэффициента соответствует одному из состояний породы (табл. 1). В данной работе приведена модификация этого критерия. Диапазоны для k1 и k2 представлены в терминах угловых коэффициентов , .
