📕 Книга "Ore Mining Methods, Comprising Descriptions of Methods of Support in Extraction of Ore, Detailed Descriptions of Methods of Development of Mines, of Stoping and Mining in Narrow and Wide Veins and Bedded and Massive Deposits Including Stull and Square-set".Unlike some other reproductions of classic texts (1) We have not used OCR(Optical Character Recognition), as this leads to bad quality books with introduced typos. (2) In books where there are images such as portraits, maps, sketches etc We have endeavoured to keep the quality of these images, so they represent accurately the original artefact. Although occasionally there may be certain imperfections with these old texts, we feel they deserve to be made available for future generations to enjoy.
