采矿工程中的原岩应力测量

Stress Measurement of Original Rock in Mining Engineering

应力测量是确定应力场性质的有力判据.原岩应力状态是影响采矿工程稳定性的重要因素之一,查明原岩应力的方向和量级是经济、安全、高效进行矿井设计、施工和生产的重要保证.它对于诸如巷道.采场布置、支护形式确定,矿井动力现象预测预防等方面都有重要的现实意义.

Stress measurement of original rock is the basis of identifying the state of stress field. The stress state of original rock is one of the most important factors that affect the stability of mining engineering. To find out original rock stress direction and quantity degree can help to assure that mine design,construction and production are economical, safe and highly efficiency, it can also help to determine the layout of roadway and face, support type, and to predict mine dynamics phenomena.
