        <p>Повышения качества геологической документации можно достичь методом фотографирования горных выработок с последующим состав­лением фотосхем, которые используются для первичной геологической документации. Такой метод прост, но возможен в том случае, когда известна отражательная способность минералов, слагающих месторож­дение, что позволяет выбрать фотоматериалы и светофильтры, дающие возможность получить наиболее контрастное разделение минералов на фотоснимке ...</p>

        <p>Improving the quality of geological documentation can be achieved by photographing mine workings and then compiling photographic schemes that are used for primary geological documentation. This method is simple, but is possible when the reflectivity of the minerals composing the deposit is known, which makes it possible to select photographic materials and light filters that give the opportunity to obtain the most contrasting separation of minerals on the photo ....</p>
