将军戈壁二号露天煤矿疏干排水设计

Design of drainage in General Gobi No.2 Open-pit Coal Mine

随着将军戈壁二号露天煤矿采剥工程位置的推进,采场出现涌水现象,面临疏干排水的问题。为了减少采场涌水对露天矿生产的影响,结合该露天煤矿水文地质勘查及采场充水因素进行全面的分析研究,提出对首采区疏干排水设计进行了深化研究与优化。确保露天开采正常进行前提下,减少地下水对内排土场及采掘场边坡稳定性的影响。

With the advancement of the mining and stripping engineering position of General Gobi No. 2 Open-pit Coal Mine,water gushing phenomenon appears in the stope, and the problem of drainage and drainage is faced. In order to reduce the influence of water gushing from the stope on the production of the open-pit mine, this article carries out a comprehensive analysis and research on the hydrogeological exploration of the open-pit mine and the factors of water filling in the stope, and puts forward that the design of drainage and drainage in the first mining area should be further studied and optimized. On the premise of ensuring the normal operation of open-pit mining, the influence of groundwater on the slope stability of internal dump and excavation site is reduced.
