The field measure of special strata freezing temperature in west area Junhao Chen, Rui Zhang College of Civil Engineering and Architecture; Anhui University of Science and Technology,Huainan 232001 China aldcjh123@163.com Keywords: west area, freezing temperature, shaft well temperature, freezing shaft sinking.
Through calculation, the frozen wall thickness, average of frozen wall temperature, shaft well temperature are meet the engineering design requirement, so propose that in west area at the freezing method mine well construction, the main purpose is waterproof, and use single circle tube freezing can satisfy engineering design requirements.
Because of inadequate understanding to the cretaceous strata, in the new shaft construction, water permeable happened more than once, engineering and technical personnel gradually realized that the only way to through cretaceous strata is using special method, and almost choose freezing method.
