        <p>Разведку месторождений асбеста все чаще ведут буровыми рабо­тами. Почти все известные месторождения хризотил-асбеста СССР разве­даны скважинами колонкового бурения. Как показывает многолетняя практика разведки этих месторождений, при опробовании керна скважин, пробуренных но асбестоносным поро­дам, несколько искажается определение содержания волокна в рудах. Это связано с относительно большим истиранием пород на отдельных интервалах керна, с перетиранием асбестового волокна при бурении. Характер самого процесса истирания керна из асбестоносных пород и степень искажения определения содержания асбеста при опробовании керна до сих пор изучались недостаточно ...</p>

        <p>Exploration of deposits of asbestos is more and more often conducted by drilling works. Almost all known deposits of chrysotile-asbestos of the USSR are explored by wells of core drilling.As the long-term practice of exploration of these deposits shows, at sampling of a core of the wells drilled on asbestos-bearing rocks, the definition of the content of fiber in ores is somewhat distorted. It is connected with relatively big abrasion of rocks on separate intervals of a core, with grinding of asbestos fiber at drilling. The nature of the process of abrasion of cores from asbestos-bearing rocks and the degree of distortion of determination of asbestos content during core sampling have not been studied sufficiently ...</p>
