掘進工安全工作注意事項

作者來源: 

導讀: (1) 掘進工必須經過煤礦培訓,考試合格,持證上崗。(2) 作業前首先要對頂幫進行敲幫問頂作業,找掉活矸活煤。堅持使用前探梁等超前支護,搭設好牢固的工作臺方可進行永久支護作業

 (1) 掘進工必須經過煤礦培訓,考試合格,持證上崗。

(2) 作業前首先要對頂幫進行敲幫問頂作業,找掉活矸活煤。堅持使用前探梁等超前支護,搭設好牢固的工作臺方可進行永久支護作業。

(3) 打頂眼時,先打中部眼,后打邊角眼。打眼過程中,更換鉆桿時一定要停風停水。

(4) 打幫眼時,應由上而下,以此打設。

(5) 安裝錨桿時,必須檢查樹脂型號、數量、先后順序,樹脂要放置正確。上錨桿時要檢查各構件是否齊全,方可安裝。攪拌器一定要與鉆機鏈接牢固。

(6) 聯網必須按作業規程要求雙絲雙扣,孔孔相聯,扭結不少于三圈。

(7) 打錨索鉆孔時,首先找好眼位,安裝和拆卸鉆桿時必須停風停水。

(8) 安裝錨索要檢查樹脂型號、數量、先后順序是否齊全。緊固錨索前檢查錨索泵壓力表是否歸零,緊固錨索要按照壓力表進行施壓,達到規定數值時停止緊固,卸下錨索千斤。

(9) 架棚作業時,首先要挖好柱窩。挖柱窩一定要挖至硬底,鑿出柱窩,達到規程規定要求。棚腿和梁要對接牢靠,檢查中線、水平位置是否合格,然后背緊背實剎桿后,把拉桿上齊,方可進行下一循環作業。
