resistant rock
解釋
抗蝕巖石-
Landslide is a geological hazard with serious losses. it is very important to research the controling methods. slide - resistant pile, which has many advantages such as high adaptability, little interference to landslide and geological environment, short construction time, high silde resistance, is a main method to control landslide. pneumatic down - the - hole hammer is a drilling method with many advantages. its features, such as wide application range, high hole quality, no circulating medium, low operation regulations, and drilling big diameter rock hole, fit to construct slide - resistant pile. according to the requirement of silde - resistant pile construction, this paper analyses feasibility that pneumatic dth hammer drilling applies to construct slide - resistant pile on the basis of introducing the features of pneumatic dth hammer. then an applied example is given
滑坡是一種危害極大的地質災害，它的整治方法研究具有重要意義.抗滑樁是一種適應性強、對滑坡穩定性和地質環境干擾小、工期短、抗滑能力強的滑坡整治方法.風動潛孔錘鉆進是一種具有許多優點的鉆進方法，它的許多特點，如成孔質量高、應用范圍廣、無液體循環介質、鉆進規程參數小、可實現大直徑基巖鉆孔等都適合於抗滑樁施工.文章在介紹風動潛孔錘鉆進特點的基礎上，根據抗滑樁施工要求，分析了風動潛孔錘用於抗滑樁施工的可行性，並舉出了其應用實例 -

The destruction resistant properties of several standard test ore pieces and natural ore blocks of various sizes were measured. the results show that the compression strength of natural ore is far less than that of standard test pieces and has the tendency of increase with the decrease of the size, which suggests that it is unrational to use the compression strength of standard test pieces to represent the destructive strength of rock ore in calculating the ball size for the coarse grinding of metal ores
測定了多種礦石標準試件及不同粒度自然礦塊的抗破壞性能，表明自然礦塊的抗壓強度遠小於標準試件，且具有隨粒度減小而增大的趨勢，也說明金屬礦粗磨機球徑計算中採用標準試件抗壓強度代表巖礦破壞性能是不合理的。 -
