湖北荆襄磷矿化学工业公司刘冲磷矿地压组成功预报了一起斜面面积达6万m~2,垮毁、塌方达100万m~3的井巷塌方事故。几年前,该地压组根据地压观测数据分析,预测井下-40m中段将有可能发生较大冒顶塌方事故。为预报及时、准确,他们坚持长达四年的观测,共获取近万个数据。尤 Hubei Jingxiang Phosphate Chemical Industry Company Liuchong Phosphate Rock Group successfully predicted a slope with an area of ​​60,000 m ~ 2, collapse, landslides reached 1 million m ~ 3 of the wellway collapse accident. A few years ago, according to the ground pressure observation data, the earth pressure group predicted that it would be possible for a large caving collapse accident to occur in the middle section of -40 m downhole. For the forecast to be timely and accurate, they insisted on four-year observation and obtained nearly 10,000 data. especially
