According to the surface deformation prediction method based on the space-time association rule, on one hand, the spatial association of the geographic information data is mined to assist in solving the problem of surface subsidence prediction in the mining process, the method can effectively and accurately identify the space-time association of the monitoring data, data errors are reduced, and the prediction accuracy is improved; high data precision and high applicability are ensured, and the method has important significance for safe and green development of mineral resources and underground water resources and safe construction of infrastructures such as subways, tunnels and highways; and on the other hand, the vector machine prediction model established based on the space-time association rule can accurately predict the future deformation value of the measuring point evolved towards the adjacent development advanced deformation area and appearing in the development delayed deformation area far away from the deformation center.

Description

technical field [0001] The invention relates to a method for predicting rock mass deformation caused in the mining process of mineral resources, belongs to the technical field of mine safety monitoring, early warning and monitoring, and specifically relates to a method for predicting surface deformation based on time-space association rules. Background technique [0002] Artificial intelligence methods are gradually applied in the mining of mineral resources, especially for various disasters and accidents caused by mineral mining, such as rock bursts and surface subsidence. Due to the instability of the rock formation, the impact on the surface begins to appear, and this impact is destructive, causing large-scale surface subsidence accidents, destroying the surface ecological environment, and endangering the safety of people's lives and property. The prediction of surface deformation determines the mine's safety. Safe mining and production. [0003] In the process of surfac...
