摘要

Abstract

Based on the measured value of the setting load,the end of the cycle resistance, the time-weighted average working resistance and frequency distribution etc. in 8120 fully mechanized working face, summarized the behavior law of mine pressure in fully mechanized top coal caving face. Research shows that: the average periodic weighting step distance of the working surface is 21.6m, the average dynamic load coefifcient is 1.67, the top coal caving caused the top coal in the face width is broken, mobile, which caused the support resistance, time weighted average working resistance is low.
