Probability Integral Method in the Influence of Ground Settlement on a Certain Construction Land

Abstract

There is a potential threat of geological hazards in the construction land adjacent to a mined-out area on the west side. To accurately determine the degree of influence of the mined-out area in this area, this article has collected and sorted out five reports on a gypsum mine since 2010, combined with various parameters in the relevant reports, and used the integral probability method. Quantitatively calculate the surface displacement value, surface tilt value, absolute value of horizontal deformation and the maximum settlement value in the goaf area. The actual calculation results show that the construction land here is not affected by the goal of the gypsum mine.
