“压实路基-铺垫路基箱”采矿方法的应用

热带雨林地区的红土镍矿地处环境雨量大，土层含水率高，进矿道路难以修筑及维护，进而导致难以出矿。为此，开创了“压实路基-铺垫路基箱”的采矿方法，有效地解决了上述问题，实现了出矿的连续，稳定。同时该方法提高了采矿效率，降低了成本，避免了二次贫化。

Application of Mining Method of “Compacting Road Base and Padding Road Base Box”

The laterite ore exists in tropic areas，where there have plenty of rainfalls and high moisture of soil layer，so it is difficult to build and maintain the access-roads to mining areas，thus resulting in difficulty to ore drawing. Based on this problem，the “compacting road base and padding road base box” mining method is conducted，which can solve the above problem effectively and achieve continuous and stable ore removal. At the same time，the mining efficiency is increased and the costs are reduced without the secondary ore dilution.
