Abstract：Combining with the mine pressure behavior of 11101fully mechanized top coal caving face in Shanxi Guocun coal mine and site measurement of high-level gas drainage roadway, the paper analyzes influence of overlying strata movement law on gas migration in adjacent seams and gas drainage effect during the initial period and normal mining period, and obtains the relationship between coal mine gas drainage peak and first weighting step and periodic weighting step and the variation law of gas emission and gas drainage amount, so as to provide references for gas control in working face.
