陕南石棉矿主产水镁石石棉,同时也产温石棉。矿山地处秦岭南缘山区,属山坡型露天矿,主采场为公路汽车开拓。建矿以来,由于没有进行正规设计,在重生产轻准备、重采矿轻剥离的思想影响下,矿山生产长期剥离欠账。到1978年底,全矿剥离欠账大体相当目前全矿4年的剥离量。矿山在这种条件下进行生产,造成了严重后果:由于没有形成正规台阶,几乎年年发生边坡塌方事故,工人经常在高达50～100米的梯壁上作业,安全难于保证;为处理和运走垮落围岩或复盖层废石,费工费时,严重干扰了正常采矿作业;采剥工作循环周期长,采、运、选不能有机地配合,生产能力得不到充分发挥;由于采剥在同一坡面上,边采、边剥、 Asbestos in southern Shaanxi asbestos production brucite, but also produce chrysotile. Mine is located in the southern mountains of Qinling Mountain, a hillside open-pit mine, the main stope for highway car development. Since the establishment of the mine, due to the lack of formal design, the production of mine has been stripped of its debts for a long time under the influence of remanufacturing light preparation and heavy mining light stripping. By the end of 1978, the whole mine stripped its debts to be roughly equivalent to the current four-year divestment of the entire mine. In the mine production under such conditions, has had serious consequences: due to the absence of formal steps, almost every year, landslide accidents occur, workers often work on the ladder wall up to 50-100 meters, the security is difficult to guarantee; for the treatment and If the working period of mining and stripping is long, the mining, transport and selection can not be organically coordinated, and the production capacity can not be fully utilized; as a result of Mining stripping on the same slope, while mining, while stripping,
