Accurate forecast and warning of landslide and debris flow disaster can help prevent and reduce disaster. The forecast of landslide and collapse is completed by disaster prevention headquarters. For the forecast of landslide and debris flow, the command system determines the specific evacuation signal. Once the danger is occurring, we can receive the alarm signal from the alarm, the gong, the horn and so on. At this time, we must evacuate to a safe high place as soon as possible. In some places, since almost every family is equipped with a mobile phone, so the headquarters will send the occurrence of disaster to the affected residents in a timely manner by sending short messages.
Influenced by the concept of "building a house around the mountains and water", many farmers in mountain cut down the hillside to build houses, which not only affects the stability of the slope, but also increases the hidden danger. When heavy rain falls, the phenomenon of group death is common. Since the 1980s, the large-scale mountain disasters in Yunnan, Sichuan and other places have caused heavy casualties and one important reason is that people lack basic prevention knowledge of mountain disasters.
In the evacating and mining of underground mineral resources, the death threats always accompany the lives of mining workers. Reports of mining disasters are also common in the media. Therefore, it is very important to understand the mining difficulties and establish and improve the emergency rescue system in the mine so as to avoid the occurrence of mining accidents scientifically. According to statistics, mining deaths accounts for 60.55% of the total industrial death, which is the highest in all types of work.
