【摘要】 锡矿山南矿采用胶结充填矿壁、尾砂充填矿房的全面充填采矿法回采河床保安矿柱,获得了较好的效果。实践证明,该法不仅技术可行,生产安全,而且经济合理,较好地解决了矿山生产上的重大课题,同时也为类似条件矿体的开采提供了借鉴。本文着重阐述了现场地压观测和研究的某些结果,并且探讨了采用该法控制采场地压和岩层移动的机理及规律。更多还原

【Abstract】 Good results have been produced in mining the safety pillar underneath the river-bed in South Xikuangshan Mine,using overall cut-and fill method in which thepillars of stopes are artificially cemented and the rooms are filled up with tailings.Practice manifests that this method is not only technically feasible and operationallysecure,but also economically reasonable.It provides a good solution for significantproduction problems of this mine and gives an example for mining such deposits ofsimilar conditions as well.This paper gives a comprehensive description of the mining method,from thestoping and back-filling processes to economic effectiveness.Some results of rockmechanics in-situ measurements and investigations as well as the mechanism and rulesof controlling the ground pessure and rock movement around the stopes,when usingthis method,are included.更多还原
