Based on the results of the forecast of the earth’s surface deformations in the zone of influence of underground mining, measures are being developed to reduce the degree of negative man-made influence on undermined buildings, structures and natural objects. Changes in mining conditions affect the decrease in the accuracy of existing forecasting techniques. For example, under the conditions of Kuzbass, the actual earth’s surface subsidence can in a great measure (by 15-25%) exceed the predicted values. Research has shown that one of the factors affecting the source of error is the depth of mining. As a result of the research, a relationship is obtained between the value of the error in calculating the maximum earth’s surface subsidence and the average depth of mining, and a method for adjusting the calculation method is proposed.
Key words: underground mining of coal seams / the earth’s surface subsidence / forecast / error / analysis of influencing factors / correction method
