当前,国内外矿山在地质探矿工作中,已较好地把坑内小口径钻探与坑探结合起来,并逐步扩大以钻代坑的范围,力求以较快的速度,较少的投资获得较好的地质效果.两年来,我们吸取了别人的先进经验,充分利用水平钻的优点,在以钻代坑探矿方面做了一些工作,并取得较好的效果. 设备和钻进参数1.设备钻机:KD-100型,5.5瓩电动机带动;水泵:配套KD泵(单缸往复式),最高泵压10公斤/厘米~2,3瓩电动机带动.钻具:小口径金刚石单动双管钻具. 2.钻进参数钻压:360～600公斤;转速:500～700转/分;泵压:2～5公斤/厘米~2. 以钻代坑的应用1.探寻隐伏矿脉石人嶂脉钨矿床的主要地质特征是:在垂深方向上呈现“五层楼”分布规律,即从
At present, the domestic and foreign mines in the geological prospecting work, the well within the pit has been well drilling and pit exploration combined, and gradually expand to drill the scope of the pit, and strive to faster, less investment to get better Two years ago, we learned the advanced experience of others and made full use of the advantages of horizontal drilling, to do some work in prospecting for drilling the pit and achieve better results. Equipment and Drilling Parameters 1. Equipment Drilling rig : KD-100 type, 5.5 瓩 motor driven; Pump: KD pump (single cylinder reciprocating), the maximum pump pressure 10 kg / cm ~ 2,3 瓩 motor driven. . 2. Drilling parameters Drilling pressure: 360 ~ 600 kg; Rotation speed: 500 ~ 700 rpm; Pump pressure: 2 ~ 5 kg / cm ~ The main geological features of the tungsten deposit are as follows: the distribution pattern of “five floors” in vertical direction is from
