Research on coal caving characteristics and caving technology for fully mechanized top coal caving mining face in thick seam with complicated parting structure;2. On the basis of mechanical property test of rock, the characteristic of combination system for coal and rock parting were thoroughly studied.

在煤岩力学性能试验的基础上，对煤矸组合系统的力学特性进行了较为深入的分析，揭示了含夹矸顶煤的破碎机理，建立了确定含夹矸层厚度上限值的方法，由此提出了提高含夹矸顶煤冒放性的主要技术措施，并在现场应用中取得了满意的效果。

The actual distribution of unload zone of coal seam ahead of working face can be shown by continuously testing the initial gas flow from coal seam during hole drilling, which can be used to forecast the outburst danger of coal roadway.

连续测定钻进过程中的初始瓦斯流量可以反映工作面前方卸压带的实际分布，从而准确地预测煤巷的突出危险性。

It was shown that coal seam floor failure depth of working face 2121 was 32.5 to 5 m, approximately three times as deep as that of shallow working face(in genera l,9.15 to 12.0 m). Coal seam floor failure depth increased with mining depth. Potential risk of water inrush through coal seam floor of working face 2121 is much higher for deep mining than for shallow mining.

试验结果表明：该工作面底板破坏深度为32.5~35 m，比300 m采深以内的工作面实测深度(9.15~ 12.0 m)增加2倍以上，说明随着开采深度的增加，煤层底板采动破坏深度呈明显增大的趋势，因此，在水压和破坏深度二者同时增加的条件下，2121工作面深部煤层开采的突水危险性远远大于浅部煤层。

At last, the rational mining method is determined as the staggered layout of coalface in the upper and the lower coal seam, with the upper coal seam is mined first and the lower coal seam is mined with the whole height.

您可以鹬第二和第三工会领袖从这一立场出发。

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。
