三棱鉆桿，又稱(chēng)三角鉆桿、防塌孔鉆桿、防抱死鉆桿，是煤礦巷道鉆探專(zhuān)用設備。其桿體采用帶有錐型過(guò)渡的三棱圓弧鋼管，接頭則通過(guò)摩擦焊接工藝與桿體連接，接頭連接形式多樣，包括螺紋式以及三角、四方、六方等樣式。?

這種鉆桿在特定地質(zhì)場(chǎng)景中應用廣泛，尤其適用于煤層及近煤層地質(zhì)條件下的鉆探作業(yè)。在煤礦生產(chǎn)中，它常被用于探水鉆孔和瓦斯排放鉆孔施工，為煤礦安全開(kāi)采提供保障。此外，在非煤礦領(lǐng)域，三棱鉆桿也發(fā)揮著(zhù)作用，可用于物探工程的相關(guān)鉆探操作，以及水利建設工程中的錨固與鉆探施工環(huán)節，適配多種工程需求，是地質(zhì)勘探與工程建設中的實(shí)用設備。
