TSP技术在矿山井巷掘进及采矿生产中的应用探讨

Discussion on the Application of TSP Technology in Mine Shaft Excavation and Mining Production

探讨使用TSP技术进行矿山井巷掘进和采矿生产过程中的地质超前预报,为即将掘进的井巷、矿体内部的地质结构及其周围的地质状况提供有用信息。通过配套软件TSP win对岩体力学参数进行评估,获得地层变化的2D和3D图像,岩体中横波和纵波的波速、岩体密度、泊松比、岩体的弹性模量等,得出矿体围岩等级、长度、空间位置,可对不良地质体的空间分布、规模和类别如断层、岩溶及含水量进行预报,为超前支护和衬砌提供依据和参数,为不同地段和不良地质体的施工和采矿生产提供施工方案和解决措施。

The paper discussed the application of TSP technology in geological prediction of mine shaft excavation and mining production process,and provided useful information for the upcoming roadway excavation,the geological structure within the ore body and its surrounding geological conditions.The mechanical parameters of rock was assessed by the matching software TSP win to obtain two-dimensional and three-dimensional stratigraphic change images,the velocity of the transverse waves and longitudinal waves in rock mass,rock mass density,Poisson＇s ratio and elastic modulus of rock mass etc..Then the grade of surrounding rock,length and spatial location can be obtained to predict the spatial distribution,and the scale and type of poor geological bodies,such as faults,karsts and water content.All these can offer the basis and parameters for the advance support and lining,and provide the construction programs and solutions for the construction of different location and poor geological bodies and mining production.
