Pregnant solution pond is one of the objects of electrometric control. They accumulate gold-enriched solutions. Identification of a breach in the waterproofing layer of a pond is possible by the method of electrical resistivity tomography with the measurement of induced polarization. Physical simulations were carried out to determine the nature of the electrical anomalies caused by the breach. A small plastic water tank imitated a solution pond. A hole was made in the bottom of the small tank, it provided a hydraulic connection with the large tank. The measurements were performed with the Skla-64 equipment, and the two-dimensional data inversion was carried out using the Res2DInv program. As a result, it was found that the place of leakage is allocated by an anomaly of low electrical resistivity and an intense anomaly of normalized chargeability. However, the 2D electrical resistivity model is complicated by inversion artifacts. The normalized chargeability anomaly is local and accurately marks the location of the leak in the bottom of the tank. It is proposed to use a complex analysis of electrical resistivity and normalized chargeability for electrometric monitoring of leaks from pregnant solution pond and other hydraulic structures.","PeriodicalId":13672,"journal":{"name":"Interexpo GEO-Siberia","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88626769","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Modern approaches to the creation of geodetic materials for solving these tasks do not meet modern requirements and do not provide the necessary level of informativeness. The authors of the article propose to use a new type of materials - vertical engineering topographic plans of scales 1: 500 and 1: 200. As a basis for a vertical engineering topographic plan, it is proposed to use orthophotomaps, digital models obtained using materials from unmanned aerial systems (UAS), converted standard topographic plans. The results of the processing of survey materials of civil buildings, obtained by means of UAS, are presented. The fundamental possibility of using survey materials to obtain vertical engineering and topographic plans at scales of 1: 500 and 1:2 00 is revealed.","PeriodicalId":13672,"journal":{"name":"Interexpo GEO-Siberia","volume":"17 4 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85564760","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is shown that the collecting agent derivatives can remove the kinetic constraint of the particle-bubble attachment, i.e. they remove water from the interlayer between a mineral particle and a gas bubble. The spreading rate of the collector derivatives governs the rate of the interlayer removal, the induction time and the collectability of this type of adsorption. The tests reveal that the increase in pH from 7 to 10 accelerates spreading of ethyl precipitates of lead xanthate over water surface from 8.5 to 15 cm/s, which correlates with the flotation performance. Based on the mechanism of physisorption, the suppression of sphalerite flotation at higher concentrations of salts of heavy metals is explained.","PeriodicalId":13672,"journal":{"name":"Interexpo GEO-Siberia","volume":"9 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72856920","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
