摘要
基于实用矿山压力理论,提出综采工作面矿压监测数据处理的4个步骤,通过时间序列矿压数据的采集和预处理,得到P_0,P_m和P_t等关键基础参数,分析其在推进方向及面长方向2个维度随时空变化的显现规律,得出上覆岩层垮落特征,评测液压支架支护质量,为工作面顶板灾变预测、控顶方案制定和支架参数的优化提供依据。
Based on practical mine pressure theory, then four steps of mine pressure monitoring data processing of fully mechanizedcoal mining face was put forward, according collection and preprocessing of time series mine pressure data, then some key base pa-rameters were obtained as P0 , Pm and Pt, and behavior regularity on two dimensions of advancing direction and working face lengthdirection with temporal and spatial variation was analyzed, collapse characters of overlying rock were obtained, supporting quality ofhydraulic supports was evaluated, it references for roof disasters forecast of working face, roof control method with temporal and spatialvariation and optimal supports characters.
