Risk Analysis on Shaft Drilling in Thick Alluvium
There are many complex and difficult problems in coalmine sinking engineering. Most risk accidents appeared in thick alluvium. This paper evaluates these risk accidents by assessment matrix after investigation. The main reasons to the accidents are summarized and the influencing factors are collected. Next, the influencing factors can be classified into several categories of risk sources. The risk weight proportions of the risk sources are calculated by Analytic Hierarchy Process (AHP). The evaluation results show that uncontrollable risk sources account for a large proportion. So, it is critical to enhance risk prediction in coalmine sinking engineering. To strengthen the engineering geological investigation is a major way to forecast risk, and to improve the engineering process can effectively lower the risk.
