以现代化矿井兴隆庄煤矿的现场实测资料为基础，对综采重复开采的覆岩破坏高度、范围、形态及发育特点等进行了全面分析，并提出：减小初次开采厚度以降低覆岩破坏高度；增大重复开采厚度以提高采煤工效和矿井经济效益；对厚煤层采用分层与放顶煤相结合的采煤方法，既可控制导水裂缝带的发育高度，又可降低生产成本。

Completed coal mining problems under three circumstances means that a coal mining face has many coal mining problems or many tasks under water bodies, building structures, and railway line. Due to a coal mining system under the three circumstances is a series of dynamic effects of overburden, ground surface, building structure and material element caused by artificial mining. Therefore the mining system is the other organized artificial system. The author shown a engineering project case. There is a water bearing stratum 25 m above the roof of the seam. The thickness of the seam is 2.5 m. On the ground surface, there are building structures needed to be protected. The paper structured a systematic physical model base on other organization theory. Then with systematic simulink software, a systematic mathematics model was built. With operation of the systematic mathematics model, a optimum limited mining depth (of 1.64 m) and optimum coal mining face terminated line (133 m to building structures) of the face to prevent the water inrush and building failure were obtained. The results shown that the method is simple and rational. The processing is direct and the calculation is samll.
