Research and application on mechanics features of mine shaft lining shrinkable connector for freezing mine shaft

RONG Chuan-xin~(1,2), CHENG Hua~(1), CAI Hai-bing~(1)(1.Department of Civil Engineering, Anhui University of Science and Technology, Huainan 232001, China;2.Key Lab of Material Mechanics Behave and Design, China Academy of Science, China University of Science and Technology, Hefei 230026, China)  
Base on the special strata conditions in Dingji Mine, a vertical shrinkable mine shaft lining structure and a new shrinkable mine shaft lining connecting form were adopted in the mine shaft lining design in order to prevent the failure and cracking occurred in the freezing wall thawing and subsidence and the under ground drainage and subsidence. After the test, the data calculation showed that under the vertical additional force, the mine shaft lining connector has good vertical compressed deformation features, high anti side stress capacity and reliable water proof and leakage features. The test results are basically the same to the data calculated results. The research results have been applied to three mine shafts in Dingji Mine.
