According to the spot experiment result of bolt anchor-hold in the condition of draining water in the roof on haulage roadway, 11201 coalface, Chengjiao coalmine, the test facility was designed independently and the influence of the anchor-hold of the resin bolt by the draining water in the drill hole was studied.

结合城郊煤矿11201工作面运输巷顶板淋水情况下锚杆锚固力现场测试结果，自行设计了实验装置，研究了钻孔淋水对树脂锚杆锚固力的影响。在现场测试中，当钻孔的淋水量小于128mL/min时，树脂锚杆的锚固力保持不变；当淋水量大于583mL/min时，树脂锚杆的锚固力比无淋水时的锚固力下降35%以上。沿巷道轴向布置卸水孔，采用集中排放，同时加大锚杆支护的密度可以改善顶板淋水时锚杆支护的效果

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.

针对当前XML数据流质量检测存在的不足，提出构建XML键的矢量矩阵作为窗口，利用矢量积小波变换多级分解与重构XML数据流，再结合最小二乘支持向量机对XML数据流质量进行预测的一种方法，满足XML数据流质量重构时实时检测的要求，保证XML数据的约束性、一致性与完整性；为了更好的适应网络负载，采取加权与自适应窗口调整等调度策略充分保证XML数据流的质量检测。
