山东会宝岭铁矿矿井水害分析与防治措施
|
摘要
会宝岭铁矿矿床产于变质岩系岩层中呈陡倾斜层状分布,矿体的主要充水含水层为二青山组灰岩、石英砂岩岩溶裂隙水。矿体顶板围岩坚硬,岩体较完整,裂隙较发育,含水性差,通过抽水试验发现富水性弱,导水性较差。矿井正常涌水量为492.8 m~3/h,最大涌水量为630.8m~3/h,井下最大突水量为256.6 m~3/h,矿井水文地质条件类型为中等型。为有效解决矿井涌水问题,确保矿井安全生产,通过采取提升矿井排水能力、设置截洪槽排放分流水量、强排水并注浆、工作面预注浆和壁后注浆等多种措施进行水害治理,取得了较好效果。
The deposit of Huibaoling Iron Mine is distributed as layered shape with steep angle in metamorphic rock mass,the watering filling aquifer of the ore-bodies is mainly for the solution fissure water of limestone and quartz sandstone of Erqingshan Formation. The roof surrounding rock of the ore-bodies is hard,the rock mass is complete,the fissure is well developed,water-containing property is poor,beside that,the pumping test show that the water-enrichment property and water-conducting property of the rock mass are both poor. The normal water inrush is 492. 8 m~3/h,the maximum water inrush is 630. 8 m~3/h,the maximum water bursting is 256. 6 m~3/h,which indicated that the hydrogeological conditions of the mine is belongs to medium type. In order to solve the water inrush problem of the mine,to guarantee safety production of the mine,the measures such as improving the mine water drainage ability,using food cutting groove to reduce water inrush,strengthen the water drainage ability and grouting scheme,pregrouting of wokring face and grouting behind the rock mass are taken to eliminate the water inrush disasters in the mine,and the good effects is obtained.
