초록

세계 성장에 따른 금속 광물의 수요 증가와, 지속된 지표 부근의 광물 개발로 인해 고심도 광산에 존재하는 광석을 안전하고 효율적으로 채굴하는 방법이 필요하다. 고심도 광산에서는 공동 주변에 집중되는 응력이 증가하며, 이로 인해 촉발지진이나 록버스트와 같은 문제가 발생할 수 있다. 또한 심부에 위치한 단층에 발파로 인한 에너지가 전달되면 단층의 미끄러짐으로 인해 지진이 발생할 수 있으며 이와 같은 사고를 제어하는 것이 고심도 광산 채광법의 핵심이다. 본 기술보고에서는 고심도 광산에서 채광 시 발생 가능한 사고를 제어하고, 생산성을 높일 수 있는 UCB(Underhand Closed Bench) 채광법에 대해 소개하고자 한다.

The increasing demand for metallic minerals due to global growth and the continued exploitation of near-surface minerals requires safe and efficient ways to mine ores present in deep mines. In deep mines, stresses concentrated around the cavity increase, which can lead to problems such as induced seismicity and rockbursts. In addition, the transfer of energy from blasting to deeply located faults can cause fault slip, which can lead to earthquakes, and controlling these events is key to deep mining methods. In this technical report, we will introduce the Underhand Closed Bench (UCB) mining method, which can control possible accidents and increase productivity when mining in deep mines.
