我队在福建滨海进行滨海相型砂、玻璃砂矿床勘探。近两年共施工57个钻孔，完成工作量1143.78米，最大孔深51.50米，钻孔可利用率100％，优质孔率达86.5％，取得了满意的地质成果，掌握了滨海相砂矿施工技术。一、原始班报表普通岩心钻探班报表不适于作为砂钻班报表，我队专门设计了“砂钻施工原始班报表”，图1表明班报表各种数字间的关系。经矿区使用，它适用于砂钻施工，原始资料齐全，完全满足地质要求。二、套管鞋我队采用锥形和锯齿形套管鞋，如图2、3所示。锥形套管鞋用
My team in Binhai, Fujian coastal sand, glass sand deposit exploration. In the recent two years, a total of 57 drilling holes were completed, with a work volume of 1143.78 meters and a maximum hole depth of 51.50 meters. The drilling availability was 100% and the high-quality hole rate was 86.5%. Satisfactory geological results were obtained and the coastal sand Construction Technology. First, the original class reports Ordinary core drilling class report is not suitable as a sand drill report, our team designed a “sand drill construction original report,” Figure 1 shows the relationship between the various figures in the class report. Used by the mining area, it is suitable for sand drilling construction, with complete original data and complete geological requirements. Second, the casing shoes I used conical and serrated casing shoes, as shown in Figure 2,3. Conical casing shoes
