                曉南礦研制新型風門皮ㄨ帶洞封堵裝置取得良好效果

                風門是礦井通風網絡♀中最常見的通風設施,其主要功能是隔斷風流。但由㊣於生產需要,經常有皮帶〗穿過風門的情況。為了@ 解決傳統風門皮帶洞封堵方式遮擋不利,漏風嚴重,致使風門阻風率下降,煤塵增大;易損壞,更換頻率較高〇等諸多不利於安全生產的因素。曉南礦利用廢舊風筒@布、皮帶等物資設計並制作了新型皮帶洞封堵裝置。該裝置目前已經應用於曉南礦二水平N1-1400運順風門坐標之時皮帶洞處。新型皮帶洞封堵裝置與傳統封堵方式相比,隔斷面積提高了20%以上,漏風率◆降低了30%以上,粉塵濃度降簡單一拳就朝其中一名玄仙砸了過去低了40%以上,且具有取材方便,安設簡單、成本低廉、使用壽命較♀長,維護頻率低∴等優點。
