Abstract
Borehole water-inflow is the key to evaluate the drilling quality of in-situ leaching of uranium. Low-permeable deposits need small inj ection volume for uranium mining hole.In well construction of in-si-tu leaching of uranium,rational and effective well drilling technology to improve and stabilize the borehole pump priming ability plays a very important role.Based on the drilling experience in well construction technologies of in-situ leaching uranium in Tong Liao,we study three key construction technologies of low-permeable deposits,including mud design,local seam reaming and flushing parameters by air compressor.关键词
