To address the oil-type gas emission hazard in coal-oil-gas coexisting mines，a quantitative risk assessment technology has been proposed. Firstly，the stability of the coal seam roof and floor strata was identified as a key parameter for evaluating oil-type gas gushing. The horizontal resistivity distribution uniformity was used to characterize strata stability. A direct current resistivity method was employed to investigate the resistivity distribution characteristics of the roof and floor strata，and a dynamic quantitative detection method for strata stability based on the resistivity variation coefficient was proposed. Additionally，comprehensive consideration of geological structures was integrated，supplemented by static parameters such as mining-induced damage depth，mechanical properties，permeability of the strata，and fault structures. Analytic Hierarchy Process (AHP) based on variable weight theory was employed to quantitatively calculate the weight of each factor relative to the evaluation indicators，thereby establishing a comprehensive quantitative evaluation method for oil-type gas gushing risks. Finally，the proposed method was applied to quantitatively assess the oil-type gas gushing risks in two typical areas of the Huangling mining area. The results align with field data from actual oil-type gas extraction boreholes，validating the method's reliability.
