大采高综采技术在三交河煤矿的实践与应用

Practice and Application on Fully Mechanized Mining Technology of Large Mining Height in Sanjiaohe Coal Mine

大采高综采技术是开采煤层厚度介于3．5～6．0m之间的综合机械化采煤技术，该技术针对煤层赋存实际情况一次采全厚，代替了以往分层开采工艺，提高了煤炭开采回采率和生产效率，推进了高产高效矿井建设。霍州煤电集团公司三交河矿针对本区煤层地质、开采条件进行了分析研究，并成功应用大采高综采技术，收到了良好效果。

Fully mechanized mining technology of large mining height is the fully mechanized coal mining technology of mining the coal seam thickness of between 3.5 -6.0 m, in connection with the actual situation of ocurrence of coal seam this technology mines overall thickness in one time, has replaced the former zonal production technique, raises recovery ratio and the production efficiency of the coal mining greatly, advances the construction of high production highly effective mine. In connection with the coal seam geology and the mining condition in Sanjiaohe coal mine of Huozhou coal electricity group, analyses and study, and succeeded application the technology, has received the good results.
