With the characteristics analysis of city gas pipeline risk as a foundation, there were many uncertainty factors in gas pipeline risk assessment, the existing risk assessment methods affected assessment results due to its own limitations. The model introduce fuzzy analytic hierarchy process, utilizing its strict logic and comparative principle, the risk factor weight of pipeline were resolved in a good solution, effectively reduce the artificial subjective, greater error and lower quantitative in the existing risk assessment methods. This method is showed through the example in city natural-gas pipeline risk assessment serviceability and reliability.

Conflicts in land exploration are incisive social problems which have been the subject in many studies. Risk assessment of land conflicts is effective to resolve such problems. Specifically, fuzzy mathematics and the analytic hierarchy process were combined together to evaluate risk in land conflicts in our work, which is proved useful to solve uncertainty and imprecision problems. Based on the analysis of the principles for the risk assessment of a land conflicts index system, a set of risk assessment indexes using the fuzzy analytic hierarchy process (FAHP) was presented. The results show that the overall risk is at medium level, and the risk of the feasibility index and controllability index need to be paid more attention to. The contribution of this article is reflected in two aspects: (1) the application of FAHP in risk assessments of land conflicts is effective and valid; (2) it is helpful for governments to establish a stricter management system of work safety for conflicts in land exploration based on the risk assessment results.

The related factors of ground movement and deformation was analyzed in coal mining, geological conditions, Analytic Hierarchy Process to establish a mining methods, mining subsidence formation time, covered lithology, mining depth and thickness ratio, horizontal deformation, curvature radius, inclination, and subsidence value of the gob as the main indicator of the type of evaluation system based on evaluation system divided into different risk levels, and to take appropriate measures to deal with different risk levels. Combined with Second West-East Gas Pipeline Ningshan branch instantiated demonstration showed Hengfa Mined subsidence gas pipeline risk assessment results coincide with the actual impact of the case, to prove that this evaluation method has great practical application guidance.
