我队施工的61号孔设计孔深为250米，终孔孔深为215米。当钻至112—114米时，由于未严格执行制度，操作时不慎，将该段地层之心全部丢失。后经物探测井、地表资料、邻近老峒……等手段推测，该段地层有含矿的可能，为验证此段地层，我们采用孔内爆破和打偏心楔的办法来进行补心。实践证明，孔内爆破和打偏心楔的方法是当前钻探生产中行之有效的、较简易的补心办法。
The construction of our team 61 hole design hole depth of 250 meters, the final hole depth of 215 meters. When drilling to 112-114 meters, due to not strictly enforce the system, operation inadvertently, the heart of the section of the strata lost. After the physical detection wells, surface data, near the old Lao ... ... and other means of speculation, this section of the strata containing ore possible to verify this section of the strata, we use the hole blasting and playing eccentric wedge way to make up the heart. Practice has proved that the hole blasting and playing eccentric wedge method is the current drilling production effective, simpler heart-beating method.
