【摘要】：工作面采高大幅提升、深部开采围岩活动加剧都要求准确获取和描述液压支架的支护状态,从而为煤矿顺利开采及综采工作面人员与设备安全提供重要数据支持。当前支架支护状态监测数据较为单一,数据获取与评价理论亟待完善。开展液压支架支护状态快速获取与模糊综合评价方法研究,研究确定支架支护状态评价关键参数;分析支架结构,确定传感系统布置方式,给出各工况下特征参数的获取及计算方法;建立支架模糊综合评价模型,计算各关键参数隶属度函数,基于变权理论确定权重系数得出支架支护状态的最终综合评价结果。该方法及数据获取系统在唐口煤矿6305工作面进行工业性试验,对液压支架保持良好支护状态起到重要作用。同时,支架支护状态实时检测与综合评价方法研究也为后续液压支架状态健康管理及自适应调控奠定技术基础。
[Abstract]:It is necessary to obtain and describe the support state of hydraulic support accurately, which can provide important data support for the smooth mining of coal mine and the safety of personnel and equipment in fully mechanized mining face.At present, the monitoring data of support support status is relatively single, and the theory of data acquisition and evaluation needs to be improved.The research on the methods of rapid acquisition and fuzzy comprehensive evaluation of the support state of the hydraulic support is carried out, and the key parameters of the evaluation of the state of the support are studied, and the structure of the support is analyzed and the layout of the sensing system is determined.The method of obtaining and calculating the characteristic parameters under each working condition is given, and the fuzzy comprehensive evaluation model of the support is established, the membership function of each key parameter is calculated, and the final comprehensive evaluation result of the support state is obtained based on the weight coefficient determined by the variable weight theory.The industrial test of this method and data acquisition system in 6305 face of Tangkou Coal Mine plays an important role in maintaining good supporting state of hydraulic support.At the same time, the research on the real-time detection and comprehensive evaluation of the support state also lays a technical foundation for the subsequent state health management and adaptive control of the hydraulic support.
