中文摘要：
将等效数值法与地下开采矿岩稳定性评价相结合，从地下开采的角度选取能够反映矿岩稳定性的5个影响指标进行评价，即实测RQD值、单轴抗压强度Rs、体积裂隙数η、隙壁状态指标Js和裂隙水指标Jw，并把矿岩稳定性等级分为5类．将该方法用于开阳磷矿用沙坝矿4种矿岩的稳定性评价中，并与模糊灰元法进行了比较．结果表明，等效数值法用于矿岩稳定性的评价。评价结果符合实际情况．该方法计算简单，便于工程人员在实际工程中应用．
英文摘要：
Equivalent value method was used assessment indexes, including RQD value, uniaxial index Js and cranny water index Jw, were selected to to evaluate the stability of underground ore-rock in this paper. Five compression strength Re, cranny number in volume, η,crack status evaluate the stability of ore-rock. The stability of 4 ore-rocks of Yong Shaba mine in Kaiyang Phosphoric Mine was evaluated by equivalent value method. Compared with the fuzzy-grey-element method, the results show that equivalent value method is available for the evaluation of stability of ore-rock and can be used in practical engineering by workers.
