A New Approach to the Problem of Protection of Undermined Objects on the Earth's Surface<bold> </bold>

Protection of undermined buildings, structures and natural objects on the earth's sur-face is to eliminate or minimize the hazardous effect of underground mining on their safe state and functioning. Based on the analysis of the provisions of the current regulatory document regulating the rules for the protection of objects on the earth's surface from the negative impact of mining operations, it was concluded that the method for determining the hazardous effect zones boundaries by means of shift angles in modern conditions of underground mining of stratified deposits is imperfect. A new approach to solving the problem of optimization of mining operations under built-up areas is proposed. This approach opens up a wide range of possible engineering solutions when planning the development of mining operations in the fields, and various options for protecting buildings, structures and natural objects located in the undermined areas.<bold> </bold>
