Abstract

Based on the monitoring data of surface subsidence in 230 mining area of Tangkou Coal Mine, the surface dynamic subsidence characteristic under deep mining subsidence and the maximum subsidence velocity were analyzed. The results showed that: in the deep mining that exceeds 300 meters, the ground surface settlement is still large, the outer boundary of subsidence basin appears the phenomenon of ground bounce and raise. The subsidence velocity of measuring points was affected greatly by mining, the high peak was basically synchronous with the mining time of working surface, surface subsidence appeared the phenomenon of concentration and slowness obviously. If only consider the effect of time, the sinking of measured point at any time can be obtained by fitting the trinomial.
