Моделирование техногенной структуризации вмещающего массива горных пород при ведении очистных работ

Моделирование техногенной структуризации вмещающего массива горных пород при ведении очистных работ

Abstract

Рассмотрены особенности геомеханических процессов при отработке пластов длинными столбами по простиранию. Показано, их следствием является формирование во вмещающем массиве иерархии структурных элементов, параметры которых связаны с упругой энергией массива и длиной очистного забоя. Обоснована параметрическая модель этих процессов, учитывающая волнообразность внешней поверхности структур как по линии очистного забоя, так и длине выемочного столба. Соответствие модели реальным газогеомеханическим процессам в углегазоносном массиве обеспечивает существенный рост эффективности технологий управления как на стадии проектирования, так и ведения горных работ. Ключевые слова: рудничная аэрогазодинамика, геомеханика, горное давление, своды давления, техногенная структуризация массива, моделирование процессов сдвижений, угольный

Geomechanical processes during coal layers long spreading pillars excavation are analyzed. It's shown, than the result is the forming of enclosing rock mass technological structuring, which parameters depends on rock mass energy and pit-face length. The parametric model of processes with structures' external surface waviness along pit-face and excavation pillar is described. The adequacy of the proposed model to real gas-geomechanical processes in coal gas-containing massif provides the essential growth of management technologies efficiency both on the project and mining stages.
