Abstract: Taking 2103 working face of Huipodi Coal Mine as an example, this paper studied the mine pressure behavior law
under the condition of soft-weak roof. Through the analysis of field measured data of mine pressure, field macroscopic mine
pressure observation and laboratory simulation of similar materials, the large and small periodic weighting law of working face was
obtained, and the structural characteristics of overburden fracture in fully mechanized coal caving mining of extra thick coal seam
under the condition of soft-weak roof were recognized, and the weighting pre-warning index was put forward, which would play a
positive role in the prevention and control of support crushing.

 Key words: soft-weak roof; first weighting; large periodic weighting; weighting pre-warning index
