为了划分出双河煤矿新区3＃煤层巷道冒顶危险区域，进而有针对性地及时采取防治措施，降低巷道冒顶事故发生率，同时节省巷道支护材料。以分析岩层稳定性的主要影响因素和获得精细地质生产资料为基础，建立顶板岩层稳定跨距计算力学模型，获得稳定跨距公式，以此为基础借助于顶板探测仪和岩层结构窥视仪等观测工具，最终得出双河煤矿巷道冒顶危险区域。区域划分对矿井和鸡西矿业集团乃至龙煤集团日后生产，具有借鉴意义和辐射作用。

In order to save the roadway supporting material and find the preventive measures to reduce the accident rates of coal mine , we try to find out the area of the roof collapse of drift in the Shuanghe No.3 Mine.The main influent factors and geological production data are analyzed as the analysis basis,the span formula was established.Based on the observation of strata structure de-tector and peep instrument, the paper found out the area of roof collapse of driftin Shuanghe No.3Mine.The research results may be of significance for the problem-solving of the roof collapse of drift .
