本文在认真分析、总结国内外露大煤矿土地复垦的理论和工程实践的基础上，应用生态学、农林学、土壤学、采矿学、水土保持、环境工程等多门学科的理论，详细论述了露天煤炭开采对区域环境的影响，提出了应用生态系统的演变规律来指导露天煤矿的土地复垦，从而实现了把复垦区水土保持和土地最终利用方向有机结合。

This paper studied the plotting of the hazard zone of Wulong mine's rockburst. This paper used ANSYS program to set up model then put up stress analysis. Taking the 311 working face of Wulong coal mine as an example, the contours of vertical stresses in the roof and floor are obtained corresponding to the mining distances of 100 m ,200 m ,300 m and 400 m respectively.It is indicated that the magnitude of vertical stress is the important influencing factor of rockburst.

用ANSYS建立模型进行应力分析，通过模拟开采3311，3l1，213工作面得到了推采距离为100、200、300及400 m 时的顶底板y向应力等值线图，指出顶板y 向应力大小是判断冲击地压是否发生的重要因素，当开采l00 m 和400 m 时工作面迎头位置产生高应力集中区，极易发生冲击地压事故。
