美国矿山局的研究认为,在矿山设计中地压控制和采矿方法的诸多进步都与岩体天然特性的研究密切相关。正在研究采前原岩应力的天然差别,以便根据原岩应力状态,制定采矿设计方案,在方案中尽量体现提高采矿效率和生产安全程度。例如,应当避开可能会发生局部岩爆的高应力区或者采取特别防范措施开采高应力区;另一方面,应力释放区可用较大的采护比进行开采。 A study by the US Bureau of Mines concluded that many advances in ground pressure control and mining methods in mine design are closely related to the study of the natural characteristics of rock mass. Natural differences in pre-mining raw rock stress are being studied in order to develop mining designs based on the stress state of the original rock as much as possible to enhance mining efficiency and production safety in the program. For example, areas of high stress where partial rockburst may occur should be avoided or special precautions should be taken to extract areas of high stress; on the other hand, the area of ​​stress relief may be mined with a larger ratio of mining and excavation.
