某矿于1970年筹建,1973年剥离完毕,由于边坡失稳,顶部开裂1.2米,各剥离梯段蠕变不止,原因不明,严重威胁安全生产。本文是笔者通过调查,对该矿边坡滑移原因提出的初步见解。一、区域地质与矿区地质根据《中华人民共和国地质图集》,该区走向北西,由三迭系复式褶皱及走向逆冲断层以及新生断陷盆地组成,褶皱断裂呈雁
A mine was built in 1970 and was stripped in 1973. Due to the instability of the slope and the cracking at the top of 1.2 meters, the creep of the peeled-off sections has more than one unexplained and serious threat to safety in production. This article is the author through the investigation, the slightest slope of the mine put forward the initial insights. I. Geology of Geology and Geology of Mining Area According to “Geology Atlas of People’s Republic of China”, the area is northwestward and consists of Triassic fold-fold and strike-thrust faults and Cenozoic rift basins. The folds and faults are geese
