基于协同回采的深部厚大矿体分段充填采矿法
Sublevel filling method for a heavy orebody in deep mining based on collaborative stoping
摘要
Abstract
To solve the problems of the precontrol roof sublevel filling method in deep mining, such as the complexity of the exca-vation process of precontrol roadway roofs and the susceptibility of precontrol roofs to blasting vibration, this article introduces a collab-orative stoping based sublevel filling method which utilizes horizontal and vertical holes at the same time. The sublevel filling method can effectively solve the roof stability problem of surrounding rock through changing the precontrol roof into a rear control roof by altering the support order. Furthermore, optimization research is performed on the sublevel filling method based on collaborative stoping:firstly, the structural parameters are optimized by stability analysis using SURPAC and ANSYS; then, the partition drawing and supporting method is applied to solve the problems of the poor support quality of the two sides and the inefficient ore-drawing. A case study of Xincheng Gold Mine shows that the displacement of the roof significantly decreases and the economic indicators improve, indicating safe and high-efficient mining of the thick and large orebody under high geostress.关键词
