Basic characteristics and starting mode of debris flow in Tieshanzhang Mining Area under typhoon

Calculation of Parameters Controlling the Occurrence of Anthropogenic Mudflows on the Dumps of the Listvennichnyi Quarry (Sakhalin)

“…Образование антропогенных селей -явление, распространенное во множестве стран мира [20,22,23,29,32,33], включая Российскую Федерацию [4,13,17,18,26]. Территория о. Сахалин также подвержена проявлению селевых процессов как природного, так и антропогенного происхождения.…”

Dynamic Evolution Characteristics and Mechanism of Surrounding Rock Fractures During the Repeated Mining of Closed Distance Deep Coal Seam

“…For example, in 2016, China's coal consumption accounted for 64% of China's total energy consumption (Fu and Liu 2017, Yang et al 2017, Grzeczka and Szymak 2016, Razali et al 2017, Azizan et al 2017. The rapid development of economy buoys the coal production, as underground coal mining depth gradually increases, even to 1000 m in some areas, and still rapidly extends to the deep at an average speed of 10 m/a -25 m/a (Xie 2017, Fan andQin 2017). Especially in the economically developed areas with a long history of coal exploitation in central and eastern China, the shallow coal resources have been nearly exhausted, and many coal mines have entered deep mining (800 m -1500 m buried depth).…”

Internal Characteristics of Loose Solid Source of Debris Flow in Zhouqu

“…However, the internal characteristics of the solid source of postearthquake debris flow are rarely reported. According to Fan et al (2017a), taking the loose solid source of debris flow in a branch valley of Nanyu Valley in Zhouqu as the research object, combined with the experiments such as cation exchange capacity, mineral chemical composition and water quality analysis, the migration law of soluble salt in solid source was compared and analyzed through soil column leaching test and soluble salt analysis, so as to study the internal characteristics of loose solid source of debris flow, thereby providing reference for the prevention and control of debris flow geological disasters.…”
