据Campair有限公司的G.里兹先生说,目前在南非的采矿场和城市工程工地,潜孔锤钻进方法愈来愈多地被期望应用于深度超过15米,直径大于100毫米的钻孔钻进中,由于潜孔锤钻进的优越性和目前高压力移动式空压机已具备实用性,因此,这种高效钻进方法将大量涌现。在许多应用中已表
According to G. Ritz of Campair, Inc., the current method of drilling downhole hammers in mining sites and urban engineering sites in South Africa is increasingly expected to be applied to boreholes greater than 15 meters in depth and greater than 100 mm in diameter In drilling, due to the advantages of DTH drilling and the current high-pressure mobile air compressor has become practical, so this efficient drilling methods will be a large number of emerge. Table has been used in many applications
