透水事故是指礦井在建設和生產(chǎn)過(guò)程中，由于防治水措施不到位而導致地表水和地下水通過(guò)裂隙、斷層、塌陷區等各種通道無(wú)控制地涌入礦井工作面，造成作業(yè)人員傷亡或礦井財產(chǎn)損失的水災事故，通常也稱(chēng)為透水。實(shí)際上其專(zhuān)業(yè)術(shù)語(yǔ)應為“突水”事故，在地質(zhì)、礦產(chǎn)等專(zhuān)業(yè)文獻中皆稱(chēng)為突水，可能在媒體在報道“突水”事故時(shí)，因方言發(fā)音等原因，誤作“透水”，而廣為流傳。

煤礦井下肋骨鉆桿的設計與應用——瑞龍鉆具

鉆桿是鉆進(jìn)工具的主要組成部分之一，在鉆進(jìn)時(shí)，通過(guò)它把動(dòng)力傳遞給巖芯管、鉆并沒(méi)有、鉆具等，由于井下地質(zhì)條件比較復雜，一個(gè)百米深的孔，極有可能即含有較軟的地層，又含有較硬的地層，傳統鉆桿滿(mǎn)足不了這種特殊條件下的鉆進(jìn)要求，給井下鉆探工作帶來(lái)很大的困難，不利于企業(yè)轉型發(fā)展，因此，找出解決難題的辦法至關(guān)重要。通過(guò)對鉆探設備、現場(chǎng)作業(yè)環(huán)境、施工地層進(jìn)行分析，對傳統鉆桿鉆探的整個(gè)過(guò)程進(jìn)行研究。傳統鉆桿主要有外平

整體式三棱螺旋鉆桿介紹——瑞龍鉆具

為解決螺旋鉆桿、寬葉片鉆桿和三棱鉆桿在松軟突出煤層鉆孔施工中易出現卡鉆、埋鉆等問(wèn)題，介紹了一種整體式三棱螺旋鉆桿，探討了該鉆桿的結構特點(diǎn)，研究了其加工工藝，并對鉆桿進(jìn)行了試制。通過(guò)對該鉆桿試樣進(jìn)行上卸扣試驗以及斷裂分析，證明鉆桿的抗扭強度達到了設計要求。該整體式三棱螺旋鉆桿配合ZDY-3200S型全液壓鉆機進(jìn)行了鉆孔工業(yè)試驗，其成孔率為100%。在煤礦開(kāi)采過(guò)程中，瓦斯抽采是防治煤與瓦斯突出和爆炸等

金剛石復合片鉆頭的維護和保養方法——瑞龍鉆具

金剛石鉆頭在鉆機和其他配套鉆探設備的配合下完成鉆探任務(wù)，作為唯一的切削巖石的鉆探配件，它是有使用壽命的，因此在每次鉆孔結束后應該及時(shí)的對其進(jìn)行維護和保養，同時(shí)這也關(guān)系到鉆頭的使用壽命。電鍍層維護和保養適當、及時(shí)的維護也可以延長(cháng)電鍍鉆頭的壽命，并可以很大程度上降低鉆探成本。及時(shí)地清洗電鍍鉆頭的頭部胎體，觀(guān)察其是否存在掉胎和剛體開(kāi)裂的情況，以及斷面金剛石的磨損程度，當鉆頭不能完成鉆進(jìn)和卡芯工作時(shí)，這是

金剛石鉆頭剛體開(kāi)裂的原因分析——瑞龍鉆具

剛體材質(zhì)???金剛石鉆頭剛體是指鉆頭胎體以下，絲扣以上的中間部分，在實(shí)際鉆探工程中，有很少一部分會(huì )出現剛體開(kāi)裂的情況，造成這種現象的原因有很多，最主要的包括剛體材質(zhì)、鉆探操作和認為造成三個(gè)原因。盡管現在金剛石鉆頭價(jià)格很低，但是因為這個(gè)原因造成鉆頭的報廢也是十分可惜的，簡(jiǎn)要分析一下這些原因的具體情況。目前我國金剛石鉆頭剛體的主要材質(zhì)為DZ50/DZ40/45#鋼這三種，其中最為常用的為DZ40，其性
