Abstract: Abstract：In order to accurately analyze the law of rock pressure, a new analysis technology of regional rock pressure in working face based on large data of support working resistance is put forward. The new concept of regional analysis of working face is defined. Based on the monitoring of working resistance of single support and the analysis of the law of strata pressure appearance, all monitoring supports in the same coal cutting cycle are divided into regions. Regional strata pressure analysis can obtain the main parameters of strata pressure appearance, such as the starting position of regional weighting, weighting step and weighting strength, which can provide information for roof management of working face Support.
