【摘要】：随着工作面支架工作阻力监测系统信息化、智能化的发展,支架工作阻力监测数据已经进入了大数据时代,尤其是基于电液控制液压支架的非测站式监测系统,每天数据采集量达数百万条,这为工作面顶板矿压显现规律分析和来压预测预报提供了数据基础。但对于海量的监测数据,目前并没有与之配套的有效分析手段。传统的人工分析方法,分析工作量较大,分析效果较差,大量压力数据并没有得到充分的分析和利用。本文基于矿压分析理论、支架工作阻力监测数据的统计特征和矿压分析专家技术经验的系统研究,准确定义了支架工作循环、支架初撑力、循环末阻力等支架工作阻力参数并提出了新的来压判别标准和分析方法,借助于Windows+.Net Framework4.0+SQL Server 2008 R2express 平台,采用 C#语言开发出一套与目前支架工作阻力监测系统配套的矿压显现规律自动分析软件。该软件可实现工作面监测支架的移架线路的实时显示;自动分析支架初撑力、循环末阻力、平均工作阻力等工作阻力参数,并以图表的形式表现;实时显示工作面推进过程中顶板压力分布情况及压力值分布比例;根据来压判别标准自动分析工作面顶板来压强度、来压步距、动载系数等矿压显现特征的参数;能对工作面开采矿压规律全程留痕;具有矿压监测数据查询及矿压分析报告自动生成功能,实现互联网+矿压的有效结合。本软件在山西煤炭进出口集团左云长春兴煤业有限公司、神华神东煤炭集团有限责任公司布尔台煤矿和大柳塔煤矿得到了成功应用,实现了工作面矿压显现特征参数的实时自动分析。应用实践表明,本软件分析准确率高,分析效果好,节约了大量人力物力,对工作面顶板管理控制具有重要的指导意义,具有较强的科学性、实用性和推广价值。
[Abstract]:With the development of information and intelligent working resistance monitoring system of working face support, support working resistance monitoring data has entered big data era, especially non-station monitoring system based on electro-hydraulic control hydraulic support. Millions of data are collected every day, which provides a data basis for the analysis of the law of roof pressure appearance and the prediction and prediction of the coming pressure. However, for the massive monitoring data, At present, there is no effective analysis method matching with it. The traditional manual analysis method has a large amount of workload and poor analysis effect, and a large number of pressure data are not fully analyzed and utilized. This paper is based on the theory of mine pressure analysis. The statistical characteristics of the working resistance monitoring data of the support and the systematic study of the technical experience of the experts in the mine pressure analysis have accurately defined the working cycle of the support and the initial support force of the support. At the end of the cycle, the working resistance parameters of the support, such as the resistance of the end of the cycle, are put forward, and a new criterion and analysis method of the pressure are put forward. With the help of Windows. Net Framework4.0 SQL Server 2008 R2express platform, Using C # language, a set of automatic analysis software of rock pressure appearance law is developed, which is matched with the current support working resistance monitoring system. The software can realize the real-time display of the moving frame line of the working face monitoring support, and automatically analyze the support initial support force. The working resistance parameters, such as end circulation resistance, average working resistance and so on, are shown in the form of charts, and the distribution of roof pressure and pressure value distribution in the process of working face advance are displayed in real time. According to the criterion of pressure determination, automatic analysis of roof pressure intensity, pressure step distance, dynamic load coefficient and other parameters can leave marks on the whole process of mining pressure law of working face. It has the function of automatically generating mine pressure monitoring data and mine pressure analysis report, and realizes the effective combination of internet mine pressure. This software is used in Shanxi Coal Import and Export Group Zuoyun Changchun Coal Industry Co., Ltd. Botai Coal Mine and Daliuta Coal Mine, Shenhua Shendong Coal Group Co., Ltd., have been successfully applied to realize the real-time automatic analysis of the characteristic parameters of coal face pressure manifestation. The application practice shows that the software has high analysis accuracy. The analysis has good effect, saves a lot of manpower and material resources, and has important guiding significance for roof management and control of working face, and has strong scientific, practical and popularizing value.
