摘　　要：传统综放工作面停采期间,保安煤柱预留宽度盲目性大,导致工作面煤柱损失量大、工作面围岩破碎严重。针对此些技术难题,决定对15314工作面停采期间采取爆破切顶预裂技术,合理确定了停采保安煤柱宽度为65 m,相比传统工作面多采出原煤量约3.11万t,取得了显著应用成效。During the shutdown period of traditional fully mechanized top coal caving face,the blind reservation of the width of the safety coal pillar results in a large loss of coal pillars and severe fragmentation of the surrounding rock of the face.In response to these technical difficulties,it has been decided to adopt the blasting top cutting pre splitting technology during the shutdown period of the 15314 working face.The reasonable width of the safety coal pillar for the shutdown was determined to be 65 meters,which resulted in an additional amount of raw coal of about 31100 tons compared to the traditional working face and achieved significant application results.
