充填和采矿方法工艺的改进,迫切需要发展在现场测定充填料的物理和力学特性的有效技术,而不是依靠传统的实验室试验。高效率采矿方法的发展要求对暴露的充填体性质有更充分的了解,以便为回采矿柱设计稳定的暴露面。在美国、加拿大和南美注意用充填空区的方法来减轻岩爆危险,还注意通过现场试验测量充填体的力学特性,以便评价充填体在矿柱回采和岩层支护中的实际作用。 Improvements in filling and mining processes have led to the urgent need to develop effective techniques for determining the physical and mechanical properties of fillings in the field rather than relying on traditional laboratory tests. The development of efficient mining methods requires a fuller understanding of the nature of the exposed filler body in order to design a stable exposed surface for the mining pillar. In the United States, Canada and South America, attention should be paid to reducing the risk of rock burst by filling in empty zones. Attention should also be paid to measuring the mechanical properties of the filling body through field tests in order to evaluate the actual effect of the filling body on pillar recovery and rock support.
