针对大冶铁矿尖林山1~#矿体大采空区(顶板水平暴露面积6434平方米,高45米)的特点,进行地质调查、振动测量、岩石力学试验、三维空间边界元分析及光弹性试验、动力模型试验。各项资料经综合研究后得出的结论是:该采空区基木稳定,在监测和限制爆破作业条件下,可以不放顶进行强采。现大冶铁矿尖林山1~#矿体已全部安全强采完毕,采终后大采空区空间尺寸为:长200米、宽78米、高73米,顶板水平最大暴露面积达9850平方米,该大采空区仍基本稳定。实践证明,本研究所作出的结论是正确的,它已取得显著的经济效益,它是岩石动力学应用于工程的一个典例,对于类似矿山的大采空区稳定性评价有借鉴意义。

This paper delt with the relationship between the floor heave and the gob height and horizontal tectonics stress in panel No.4 in U.S.King No. 4 coal mine, which was investigated by using a hybrid boundary element—finite ele ment method of stress analysis. According to the calculation results, such conclu sions, the larger gob and larger horizontal tectonic stress are the important causes to induce the floor heave, etc., were discovered in the paper. 4flgs, 2tabs., 4refs.
