对岩层及地表移动规律的观测、室内试验和数值计算分析表明,采动覆岩层沉陷运动的不协调性造成裂隙带上部弯曲带岩体中产生大范围的离层空隙。随着工作面的推采,离层空隙周期性悬露垮断构成了上覆岩层及地表移动变形运动的不同特征。根据现场观测,砾岩层运动是矿井冲击地压发生的主要力源,地表下沉速度发生剧烈变化,冲击地压发生的频率较高,地表产生反弹时更为危险,且随着砾岩层的运动,冲击地压发生周期性变化。

中阶梯光栅光谱仪二维谱图中,信号光斑位置的提取精度直接影响光谱分析精度,是中阶梯光栅光谱仪研制中的关键问题之一。为保证中阶梯光栅光谱仪的高分辨率特征(其分辨率一般为几千以上,本仪器光谱分辨率为15 000),信号光斑的位置提取误差应小于0.03mm(小于2个像素)。在分析中阶梯光栅光谱仪谱图特征的基础上,提出了一种基于质心法的信号光斑位置提取算法,即通过搜索信号光斑探测窗口进行光斑判读以及信号光斑质心计算,实现了信号光斑位置的精确读取。实验结果表明,采用该算法可以有效地去除噪声光斑的干扰,实现信号光斑位置的快速精确读取,位置提取误差小于2个像素,波长误差小于0.02nm,满足本仪器要求。
