我队在金矿普查中施工浅井，在岩层十分坚硬的条件下，利用争光—10型取样钻机打炮眼，即在浅井的预定部位，把炮眼一次打到浅井的计划深度，然后分段爆破成井，取得了满意的效果。一、地质条件施工区地表为第四系洪积砂砾层，厚度在0.5～1.5米之间，约为3—4级。矿层为褐铁矿化石英脉破碎带，厚薄不一，约为5—7级；含矿石英脉为8—9级；围岩为凝灰质砂岩，绿泥石化凝灰质砂岩等，致密坚硬，为7—9级。浅井就是布置在破碎带上穿入围岩，弄清岩矿产状。
Our team constructed the shallow wells in the gold mine survey and shot the blasthole with the Zhenguang-10 type sampling rig under the condition of very hard rock formations, that is, blasting the blasthole to the planned depth of the shallow well once at a predetermined part of the shallow well and then blasting the wells into sections , Has achieved satisfactory results. First, the geological conditions Construction area of the surface of the Quaternary alluvial gravel, the thickness of 0.5 to 1.5 meters, about 3-4. The ore layer is limonite fossil British vein rupture zone with different thickness, which is about 5-7 grade; the ore vein is 8-9 grade; the surrounding rock is tuffaceous sandstone, chlorite tuffaceous sandstone, etc., dense and hard, For the 7-9 level. Shallow wells are arranged in the broken belt to wear rock, rock and mineral clarification.
