| 摘 要： | 针对宝山-振兴煤田第三系煤田地质勘探中地层松散,易坍塌、掉块、缩径的问题,采用普通双管和普通绳索取心钻进,各有利弊,而将SA75绳索取心钻具钻头、扩孔器加大到Φ80 mm,并采取相应的钻孔、取心技术措施,取得了质量高、效率高、效益好的成果。

| Abstract: | According to the loose stratum,easy collapsing,block-falling and hole diameter shrinkage in the tertiary coalfield exploration for Baoshan-Zhenxin coalfield,application of general double-tube and wire-line coring drilling have their own advantages and disadvantages.But by enlarging SA75 wire-line coring drilling tool and hole reamer to 80mm in diameter with corresponding measures of drilling and coring,high quality,high efficiency and preferable benefit were achieved. |

| Keywords: | coalfield exploration wire-line coring tool hole diameter shrinkage collecting rate of core coring hole completion |
