工作面合理回采速度是矿井安全稳定生产的前提，开采沉陷是回采速度和煤矿冲击地压灾害的关联参量。为了弄清工作面回采速度、沉陷参数、冲击显现的关系，以内蒙古红庆梁煤矿11302工作面为工程背景，实测分析了工作面开采全时期内的地表沉陷规律，明确了地表移动动态参数，分析了工作面回采速度与沉陷参数、沉陷参数与微震事件的函数关系表达，以降低微震事件数为判别依据，得到了基于不同地表沉陷参数下的工作面合理回采速度。结果表明：工作面走向和倾向最大下沉量分别为2 460 mm和2 073 mm，下沉系数为0.47；超前影响范围和平均下沉速度均随着回采速度增大而减小；超前影响角随着回采速度增大而增大，拟合系数均超过0.65。相邻观测时期的微震事件总数和单日平均微震事件数随3个沉陷参数的增大而分别减小、减小和增大。微震事件整体较低至快速升高临界条件下的超前影响角、超前影响范围、米平均下沉速度和日平均下沉速度分别为60.6°、253 m、3.41 mm/m、26.4 mm/d，工作面回采速度低于7.30 m/d时，不同沉陷参数下的矿山微震显现程度均较弱，有利于降低冲击灾害风险。研究结果为地表沉陷观测下的工作面回采速度防冲方法提供了理论依据。

The rational mining speed of a working face is considered a prerequisite for safe and stable production in mines. Mining subsidence is regarded as a correlating parameter between mining speed and coal bump disaster. To clarify the relationship among the mining speed of the working face, subsidence parameters, and coal bump behavior, the 11302 working face of Hongqingliang coal mine in Inner Mongolia was taken as the engineering background. The surface subsidence patterns during the entire mining period were measured and analyzed, and the dynamic parameters of surface movement were determined. The functional relationships between the mining speed and subsidence parameters, as well as between subsidence parameters and microseismic events were analyzed. With the reduction of microseismic events as the criterion, the rational mining speed of the working face based on different surface subsidence parameters was obtained. The results indicate that the maximum subsidence along the strike and dip directions of the working face are 2 460 mm and 2 073 mm, respectively, with a subsidence factor of 0.47. The advance influence range and average subsidence velocity are found to decrease with increasing mining speed, while the advance influence angle increases with mining speed, with fitting coefficients exceeding 0.65. The total number of microseismic events and the average daily number of microseismic events during adjacent observation periods decreases, decreases, and increases, respectively, with the increase of these three subsidence parameters. The critical conditions for the transition from overall low microseismic events to rapid increase are identified as an advance influence angle of 60.6°, an advance influence range of 253 m, an average subsidence velocity of 3.41 mm/m, and a daily average subsidence velocity of 26.4 mm/d. When the mining speed of the working face is below 7.30 m/d, the behavior of mine microseismic events under different subsidence parameters is relatively weak, which was beneficial for reducing the risk of coal bump disasters. The research results provide a theoretical basis for the coal bump prevention method of working face mining speed under surface subsidence observation.
