新年新起點(diǎn)我地質(zhì)鉆桿廠(chǎng)家緊抓機遇求發(fā)展

時(shí)間的腳步把我國的經(jīng)濟帶入到了又一個(gè)新的高度，隨著(zhù)我國各項的政策不斷的完善，全國的基礎建設、高速公路等大型的施工工程在人們熱火朝天的干勁中展開(kāi)，在施工中理所當然的離不開(kāi)地質(zhì)鉆桿的使用，也因為如此為我國礦山施工機械行業(yè)帶來(lái)了空前的發(fā)展機遇。????從市場(chǎng)需求的增長(cháng)來(lái)看，地質(zhì)鉆桿設備求過(guò)于供，主要來(lái)自于設備獨有的施工優(yōu)勢，在施工方面地質(zhì)鉆桿有著(zhù)它讓其它設備望塵莫及的特點(diǎn)；市場(chǎng)需求的增長(cháng)同樣帶動(dòng)了設備更

什么是煤礦采空區——瑞龍鉆具

是指在煤礦作業(yè)過(guò)程中，將地下煤炭或煤矸石等開(kāi)采完成后留下的空洞或空腔。在對煤礦開(kāi)采過(guò)程中，采空區常常給煤礦的正常生產(chǎn)帶來(lái)危害。由于在煤礦開(kāi)采過(guò)程中采空區存在大量的遺留的浮煤，浮煤的存在為煤礦自燃提供了物資條件。煤礦自燃嚴重威脅著(zhù)煤礦的安全生產(chǎn)、制約著(zhù)煤礦的生產(chǎn)，而采空區煤礦自燃在煤礦自燃發(fā)生總體中占有重要的部分。我國國有重點(diǎn)煤礦中采空區煤礦自燃占自燃火災的60%，其中絕大部分火災是有漏風(fēng)引起的。有

頂板事故發(fā)生的原因——瑞龍鉆具

1、采空區頂板跨落不好，懸頂面積過(guò)大；?2、頂板中存在斷層、裂隙、層理等地質(zhì)構造，將頂板切割成不連續的巖塊，回柱后巖塊失穩，推倒支柱造成冒落；?3、回柱操作順序不合理；?4、工作面支護不好，支護密度不夠，初撐力低，迎山角不合理等；?5、在遇見(jiàn)未曾遇見(jiàn)的地質(zhì)構造時(shí)，沒(méi)及時(shí)采取措施；?6、工作面上、下出口連接風(fēng)巷和運輸巷，控頂面積大。兩巷掘進(jìn)時(shí)經(jīng)受壓力重新分布的影響，同時(shí)因為巷道初撐力一般較小，使直接

什么是頂板事故？——瑞龍鉆具

頂板事故是指在地下采煤過(guò)程中，頂板意外冒落造成人員傷亡、設備損壞、生產(chǎn)終止等的事故。過(guò)去，頂板事故據資料顯示占全部死亡人數的40%以上?，F頂板事故雖有減少，但仍是煤礦生產(chǎn)的主要災害之一。
