Экспериментальная оценка геомеханического состояния краевых частей пластов и целиков на шахтах АО «СУЭК-Кузбасс»

Экспериментальная оценка геомеханического состояния краевых частей пластов и целиков на шахтах АО «СУЭК-Кузбасс»

Abstract

Приводятся данные экспериментальных исследований по прогнозу удароопасности пласта методом буровой мелочи на шахте им. А. Д. Рубана АО «СУЭК-Кузбасс». Полученные данные позволили оценить геомеханическое состояние краевой части пласта: установить величину максимума опорного давления и расстояние до него. Произведено сравнение теоретических значений параметров опорного давления с параметрами, полученными экспериментально. Результаты исследования можно использовать для корректировки теоретических моделей расчета геомеханического состояния пологих угольных пластов и оценки устойчивости целиков.

The article contains findings of experimental research of rock bump hazard forecast by using a drill cuttings method at Rubana Mine, JSC SUEK-Kuzbass. The obtained data have facilitated evaluation of geomechanical condition of the edge of the seam: to determine the maximum abutment pressure and distance to it. Theoretical values of abutment pressure parameters were compared with experimental data. Research findings can be used for adjusting theoretical models for calculation of geomechanical condition of gently dipping coal seams and evaluation of pillar stability
