The present status and the key issues to be resolved of thick seam mining technique in China
Journal Title: Science Paper Online - Year 2008, Vol 3, Issue 11
Abstract
This paper introduces the state of the art and the development of thick seam mining techniques in details and the prominent achievements in top-coal caving and large cutting height workface in China. It is pointed out that proper mining method shall be adopted according to the thick seam coal mining conditions and technical conditions. With the increase of coal seam thickness and exploitation degree, many issues need to be resolved imminently, such as improving the recovery rate of coal resources, selection of proper support method, and gas movement law and control techniques.

CuxTe背接触层对CdTe光伏器件性能的影响
研究了由共蒸发制备出的CuTe多晶薄膜的性能及其对CdTe光伏器件性能的影响。研究表明，刚沉积的CuTe薄膜为非晶相，退火后，随着退火温度的升高，不同配比的样品有着不同程度的物相转变，其中Cu/Te为1∶1.44的薄膜多晶转变最为明显，结晶度...
薄纤维层吸声理论和实验研究
薄纤维层如织物、无纺布等既是室内装饰材料，又具有较好的吸声作用。然而根据传统微孔吸声理论，薄纤维层由于微孔通道太短而只能有很小的吸声作用。但是，在背后有空腔时薄纤维层却表现出良好的吸声效果。说明薄纤维层可能具有某种新的吸...
