The complex character of open pit mining’s harmful influence on the environment requires integrating efforts of government, universities, research organizations and mining enterprises for cooperative solving of ecological problems. One of the kinds of such cooperation is a technological platform of geo-ecology which must inspire mining enterprises to implement innovative technologies of quarry wastewater purifying to the norms of maximum permissible concentration. The main advantages of wastewater filtering technology described in the article are the low cost and ability to substitute expensive water treatment facilities. This is especially important due to match tightening ecological requirements for mining enterprises set by government in many countries. The innovativeness of proposed technology is that it makes possible to use overburden rock and machinery currently exploiting at open pits to create filter arrays. The article contains description of a stepwise research of implementing of the new technology of quarry water purifying using filtering arrays with proved efficiency.
