“快钻勤提”即是在钻进过程中，适当地缩短钻进时间，合理地增加提钻次数，充分发挥和利用切削工具在井底工作的最大效能，尽量获得最高的钻进速度。经验证明，“快钻勤提”，在合金钻进中，尤其是在煤田300公尺左右的中浅孔钻进，是提高效率。保证质量的有效措施之一。东北煤田勘探局104队耿孝金钻机，五六年即在平均孔深300公尺的孔，创造了1600公尺以上的台月效率，而轰动全国。五七年七月赴该队观摩学习，知道他们在150—200公尺深的孔，一个小班（八小时）内，钻进回次最高达12次之多，一般每一回次钻进时间均不超过一个小时，但平均单位小时进尺却达4.4公尺以上，煤层及共他质量也全面满足了地质要求。
“Drilling and Diligence” refers to the drilling process, the appropriate shortening drilling time, reasonable increase in the number of drilling, give full play to and use of cutting tools in the bottom of the maximum efficiency, try to get the highest drilling speed. Experience has proved that “fast drilling diligence”, in alloy drilling, especially in the coal field about 300 meters of shallow holes drilling, is to improve efficiency. One of the effective measures to ensure quality. The 104 drilling teams of the Northeast Coalfield Exploration Bureau, Geng Xiaoguang, bore holes of an average hole depth of 300 meters in five or six years, creating an efficiency of more than 1,600 meters on the Taiwan Moon and causing a sensation throughout the country. Go to the team in July, July and watch the study to learn that they drill in 150-200 meters deep hole, a small class (eight hours), up to 12 times as many times as drilling, generally each time the drilling time Not more than an hour, but the average unit length of footage is up to 4.4 meters above the coal seam and his total quality also fully meet the geological requirements.
