金川镍矿是我国最大的硫化铜镍矿,以地应力高、矿体厚大和矿岩不稳固著称国内外采矿界。该矿体开采难度之大、充填成本之高备受国内外采矿界关注。近年来,随着矿床开采深度逐年增加已接近千米,采场面积超过1×105 m2,高温、高压和高渗压的“三高”采矿环境日趋显著,不仅提高了采矿成本,而且还给矿山安全高效生产带来巨大压力。本文首先概述金川深部矿床采矿技术条件,然后明确采矿生产面临巷道和采场稳定性控制技术难题,分析采场围岩变形和岩层移动所潜在的灾变失稳风险。最后提出了金川深部矿体安全高效开采亟待攻克的技术难题,为金川深部资源开发能力和综合利用指明了方向。
金川鎳礦是我國最大的硫化銅鎳礦,以地應力高、礦體厚大和礦巖不穩固著稱國內外採礦界。該礦體開採難度之大、充填成本之高備受國內外採礦界關註。近年來,隨著礦床開採深度逐年增加已接近韆米,採場麵積超過1×105 m2,高溫、高壓和高滲壓的“三高”採礦環境日趨顯著,不僅提高瞭採礦成本,而且還給礦山安全高效生產帶來巨大壓力。本文首先概述金川深部礦床採礦技術條件,然後明確採礦生產麵臨巷道和採場穩定性控製技術難題,分析採場圍巖變形和巖層移動所潛在的災變失穩風險。最後提齣瞭金川深部礦體安全高效開採亟待攻剋的技術難題,為金川深部資源開髮能力和綜閤利用指明瞭方嚮。
