Abstract. This article describes the methodology and results of the application of underground gravity exploration in the study of polymetallic mineralization around the mine. Based on the features of changes in the nature of gravitational anomalies, ore bodies located both above and below the mine workings were identified, the possibilities of underground gravity exploration when searching for disturbing bodies in the near-worked space, the technique of underground measurements of gravity field elements, processing of observation results and methods for identifying local anomalies, the technique of interpretation of gravitational anomalies taking into account the conditions of mining. Specific examples show the geological efficiency of underground gravimetric studies in various physical and geological conditions when solving prospecting and exploration tasks. When setting up gravimetric work on deposits of the contact-metasomatic type, the main task is to establish the possibility of high-precision gravimetric survey of ore bodies, to clarify complicating factors and the necessity of their accounting. A feature of the distribution of a polymetallic deposit is the complexity of its formation both in depth and horizontally. According to the results of the autopsy of the bodies, there is a frequent alternation of relatively rich and poor ore bodies. Basically, the ore bodies have a columnar shape and have a steep declination of the south-eastern direction.
