TY - Data T1 - Data set of observation point displacement values of indoor similarity test model of dahazi coal mine in Yulin City, Shaanxi Province (December 2020) A1 - Zhao Yiping DO - 10.12072/ncdc.UTCMW.db2135.2022 PY - 2022 DA - 2022-05-30 PB - National Cryosphere Desert Data Center AB - In order to deeply analyze and study the characteristics of overburden failure and fracture development under mining dynamic load, displacement observation points and stress observation equipment are installed in the model to intuitively analyze the characteristics of formation displacement change and stress distribution. Layout of displacement points in the stratum: take 2cm away from the top of the mining coal seam as the first row (55 observation points are arranged in each row, with an interval of 5cm. The observation points are numbered as 1-1, 1-2, 1-3, 1-4, 1-5, 1-6, 1-7... From the cutting hole back). A total of 22 rows are set in the model from bottom to top.The data set contains 729 groups of data. DB - NCDC UR - http://www.ncdc.ac.cn/portal/metadata/0c10f187-bbf0-4e39-b3ba-334039c7becf ER -
