近水平绳索取心钻探技术在寨上金矿复杂地层中的应用
Application of near-horizontal wireline core drilling technology in complex strata of Zhaishang Gold Mine
摘要
Abstract
In the exploration project of the Zhaishang Gold Mine in Min County,Western Qinling Mountain,drilling work was carried out to control the main ore veins in the southern ore belt of the mining area.According to past experience,the main ore veins in the southern ore belt have steep occurrences(78°～85°)and are unstable,characterized by a southward dip in the shallow part and a northward dip in the deep part.At the same time,most areas have thick overburden layers,with intense topographic cutting,making it difficult to roads and airports construction and drilling equipment transportation.The first near-horizontal borehole in the mining area was designed,where the EP1000 portable full-hydraulic drill was used,the horizontal drill frame kit was transformed,upgraded and processed,wireline coring technology was adopted,and the construction of a near-horizontal coring borehole with a length of 216.73m was completed.This is an innovation to implement a near-horizontal borehole under the condition of water-sensitive,complex strata and continuous water gushing in the borehole.It practices the concept of green exploration and provides a reference for similar engineering projects.关键词
