摘要: 为实现煤矿工作面矿压规律的精准分析,提出了工作面区域矿压分析理论,明确了工作面矿压分析的区域概念、区域矿压显现特征参数及区域划分流程,从而提出了基于支架工作阻力大数据的工作面区域矿压分析技术。并以营盘壕矿2101工作面矿压分析为例,对工作面中部区域的单架和区域矿压规律进行对比分析,得到区域矿压分析结果与实际矿压规律吻合度较好,区域来压能反映区域内大部分单架的来压特征,基于支架工作阻力大数据的工作面区域矿压分析技术能够对工作面矿压规律进行精准分析。

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.
