Abstract: In order to investigate the pressure relief effect of 02^# coal seam of Zhongxing Coal Industry Co., Ltd. on 2^# coal seam
under protection after mining, this paper took 3203 working face as the research object, and measured and analyzed the relevant
parameters before and after the mining of 2^# coal seam under protection, and investigated the changes of gas volume fraction on
the protected layer surface. Through the research, it summarized and studied the changes of relevant parameters before and after
the protective layer mining, which provided a theoretical basis for the safe mining of similar working faces.

 Key words: short-distance; protective layer mining; pressure relief effect; gas volume fraction
