煤礦坑道智能化鉆探技術(shù)發(fā)展框架分析瑞龍鉆具

坑道智能化鉆探的顯著(zhù)特征在于智能鉆具的研發(fā)與應用和鉆探數據的獲取與分析，但現階段我國煤礦坑道智能化鉆探的研究基礎較為薄弱，坑道智能化鉆探缺乏科學(xué)化、精細化的技術(shù)手段，且缺乏系統性發(fā)展框架。針對該問(wèn)題，闡述了我國煤礦坑道智能化鉆探技術(shù)研究現狀，從自動(dòng)化鉆機、導向鉆進(jìn)技術(shù)、孔內多參數獲取、智能分析決策等方面總結了煤礦坑道智能化鉆探發(fā)展成果與不足；在此基礎上提出了煤礦坑道智能化鉆探技術(shù)發(fā)展框架，指出應圍繞精準導向系統、數據測量系統、數據傳輸系統、智能決策系統和自動(dòng)控制系統，打造從孔底到孔口、從井下到地面的一體化坑道智能化鉆探平臺，構建“參數測量-〖智能決策-控制執行”坑道鉆進(jìn)過(guò)程閉環(huán)控制系統：通過(guò)數據傳輸系統將孔底隨鉆測量參數實(shí)時(shí)傳輸至地面遠程數據支持中心，采用人工智能算法對地質(zhì)參數、幾何參數和工程參數進(jìn)行協(xié)同分析，并實(shí)時(shí)更新三維可視化地質(zhì)模型，制定鉆進(jìn)工藝參數和鉆孔軌跡智能調控策略，控制井下智能鉆機工作。
