During the long-term operation of the uranium deposits of the Streltsovsky ore field, the experience of conducting operational exploration (ER) at the mines of the enterprise of PJSC “PPGHO” has been accumulated. The analysis of this experience and the experience of mining enterprises in related industries allowed us to develop an effective system for conducting these works.
The information obtained at the stage of detailed exploration of deposits is quite sufficient for the design and construction of a mining enterprise, but it is not sufficient for drawing up local projects for mining individual ore bodies and deposits. Therefore, more detailed information is required about the parameters of ore bodies, their structure and reserves of useful components in ores. For these purposes, operational exploration is carried out, which accompanies all stages of mining operations.
Operational exploration is carried out by sinking mining workings and drilling underground wells and boreholes from these workings. At different stages of mining operations, different technologies are used, consisting in the formation of a certain exploration network, which makes it possible to obtain sufficient mining and geological information for the successful completion of a certain stage of mining operations. At PJSC “PPGHO”, a system for conducting operational exploration was developed, consisting of three stages: Stage I for designing the mining of a part of an ore deposit in the contour of a certain operational block, stage II for designing rifling operations, stage III completes the development of block reserves and is designed to control the completeness of the extraction of minerals. Each subsequent stage of the ER has a denser exploration network compared to the previous one by about 2 times.
Based on the accumulated experience, the standard of the enterprise for conducting operational and exploration works-STP 76-80, which sets out the goals and objectives of the ER, the methodology of the work, the density of the exploration network and organizational issues for conducting the ER has been developed.
During the implementation of the ER, information has been obtained that allowed the enterprise to successfully extract uranium ores, ensuring uninterrupted supply of the ore processing production with the necessary quality of raw materials
