整體式鉆桿的施工工藝 瑞龍鉆具

松軟煤層是指煤的硬度系數f<1的煤層，具有煤質(zhì)松軟，滲透性差，瓦斯含量高、壓力大等特點(diǎn)。瓦斯抽采鉆孔施工過(guò)程中，容易發(fā)生噴孔、塌孔、抱鉆等孔內事故，導致鉆孔成孔深度淺、成孔率低、瓦斯抽采效果差等問(wèn)題，已成為煤礦開(kāi)采亟待解決的難題。

在長(cháng)期的鉆探實(shí)踐中，國內一些煤礦企業(yè)先后進(jìn)行了松軟煤層空氣鉆進(jìn)技術(shù)的試驗與應用。采用寬翼片螺旋鉆桿配合風(fēng)壓鉆進(jìn)技術(shù)以后，松軟煤層的成孔深度和成孔率有了大幅度提高，而中風(fēng)壓空氣鉆進(jìn)技術(shù)成為松軟煤層中一種有效可行的鉆孔施工工藝。
