Surface Movement Parameters and Practice Effect of Strip Mining under Thick Alluvium and Thin Bedrock

HU Bing-nan,ZHAO You-xing,ZHANG Hua-xing(Coal Mining Technology Dept,Tiandi Science & Technology Co.Ltd,Beijing 100013,China)  
The angle dimension parameters of surface movement,tokens of space shape,are analyzed in this paper based on the observation data of strip mining under thick alluvium and thin bedrock.The surface movement parameters of routine strip mining are optimized.The surface movement parameters calculated in narrow face are fit to calculate the surface movement parameters of short-wall face of broad strip in insufficiency mining.The practice shows that high output and high efficiency may be gained even in strip mining if only rational technology and equipments are adopted.
