Abstract

According to the effective control of brittle coal caving mining face large and sudden piece rib spalling , based on the analysis of brittle coal mechanical properties and microstructure, the numerical simulation method was adopted to analyze the changing rule of the coal stress of working face ahead and coal displacement horizontal displacement, combined with field observation analysis for skiving mechanism of brittle coal. And through the field observation of coal wall rib spalling mechanism verification, the reasonable coal wall stability control technology was formulated, which provided reference basis for similar conditions of the coal wall.

Key words： brittle coal mining caving face coal wall rib spalling mechanism control technology
