摘 要:针对厚表土层地区煤矿井筒偏斜及安全预警问题,采用光纤光栅倾角仪建立了井筒偏斜量监测系统,获得了井壁偏斜量的变化规律,采用R/S分析法对井壁偏斜量监测数据进行了深入分析。研究表明,光纤光栅倾角仪可用于井筒偏斜量的监测,监测时段内井筒最大偏斜量为0.1469 m,在安全范围内。R/S分析表明,监测数据的Hurst指数介于0.6094与0.9964之间,符合正偏随机游动过程,具有较强的正向持续性,未来一段时间内,井筒偏斜的发展过程将持续现有发展趋势。井筒偏斜量发展规律的最小观察时间尺度应不小于15 d。A monitoring system for coal mine shaft deviation and safety warning in areas with thick soil layers was established using a fiber Bragg grating inclinometer.The variation law of shaft deviation was obtained,and the R/S analysis method was used to conduct in-depth analysis of the monitoring data of shaft deviation.Research has shown that fiber Bragg grating inclinometers can be used for monitoring wellbore deflection,with a maximum deflection of 0.1469 m during the monitoring period,which is within a safe range.R/S analysis shows that the Hurst exponent of the monitoring data ranges from 0.6094 to 0.9964,which conforms to the positive biased random walk process and has strong positive persistence.In the future,the development process of wellbore deviation will continue to follow the existing development pattern.The minimum observation time scale for the development law of wellbore deflection should not be less than 15 days.
