摘要

Risk evaluation is an important tool to per evaluate the potential hazards, which involves not only the natural characteristic of hazard, but also the socioeconomic properties of the vulnerability. Therefore risk evaluation is a complicated and important scientific problem. According to the analysis of the developed characteristic, forming condition and influent factors of the mining collapse in mountain area in Beijing, this paper gives the index system and methods for hazard evaluation and vulnerability evaluation. The risk evaluation equation is "Risk = Hazard × Vulnerability". And the risk degree is classified to 5 grades. Based on these methods, Mentougou District is chosen as an example to evaluate its risk degree of the mining collapse and draw its zoning map of the risk grades. The evaluation result is coincidence with the actual situation. It can be a foundation for the collapse controlling in this district. The method can be taken as an example for evaluation of mining collapse in other mountains in Beijing.
