近十几年来,锚喷支护已在我国煤炭、冶金矿山迅速推广使用。在学习国内矿山成功经验的基础上,浦市磷矿于1975年开始试用,截止1978年底为止,应用锚喷支护的井巷计有3300米,占全矿井巷工程支护总长度的55.1％;绝大部份锚喷井巷经受了两年以上的生产使用检验,一般情况良 Over the past decade, anchor spray support has been rapidly promoted in China’s coal, metallurgical mines. On the basis of the successful experience of studying domestic mines, Pu Shi Phosphate Rock began trial operation in 1975. Up to the end of 1978, the mine with anchor and shotcrete support had a total length of 3300 meters, accounting for 55.1% of the total support length of the entire mine roadway. ; Most of the anchor spray lanes have been subjected to more than two years of production and testing, generally good
