摘要
五龙金矿是辽东矿集区的大型石英脉型金矿床,累计黄金储量超过80 t,但随着开采量的增加,目前该矿床开采深度达近千米,保有储量不断减少,所以亟须开展矿区深部找矿研究。在以往研究的基础上,通过钻头胎体配方、金刚石参数及钻头结构等研究,试制高胎块金刚石取芯钻头。现场试验表明:钻头效果显著,机械钻速为1.4 m/h,钻头寿命达到132.2 m,解决了该矿区钻头钻进效率低、使用寿命短的问题。
The Wulong gold deposit is located in the ore-concentrated district of eastern Liaoning Province.It is a large quartz vein type mine hosting more than 80 tons of gold.However,with the increase of mining volume,the mining depth of the deposit is nearly 1 km,and the retained reserves are decreasing.Therefore,it is urgent to carry out deep prospecting research in the mining area.On the basis of previous studies,a high matrix diamond coring bit was developed through the study of bit matrix formula,diamond parameters and bit structure.The field test indicates that the bit effect is remarkable and that the problems of low drilling efficiency and short service life of original bits in this mining area have been solved.
