神东矿区补连塔煤矿井下水复用方案择优

对补连塔煤矿井下水复用的三个可行方案进行了简述,给出了采空区溶滤、井下水仓及地面水仓三种方案的工程总投资、地面管路钻孔费、年新增费用和工程施工条件等具体评价指标值,用多目标决策中加权相对偏差距离和定量指标综合决策两种方法进行了方案择优,并对选择结果进行了相互验证。所选出的井下水仓方案具有较高的可靠性,实施后实际矿井给水能力可达3 000 m3/d,矿井采用这一优化的供水工程方案取得了较明显的效果。

Scheme choice for reusing Bulianta coal mine water of Shendong mining area

Three feasible schemes of reusing the water under Bulianta coal mine have been stated,and the project total investment of the three schemes for dissolving and filtering of empty area,water storehouse inside and outside the mine has been given.Some concrete index values of evaluating about the pipeline borehole wastes on the ground,the new wastes every year and the wastes of carrying out the project are given.We choose the optimal scheme by two ways,which are the weighting relative deviation distance and the synthetical decision of quantitative index in the multiple target decision.We also validate the choice result one another.The choice scheme about water storehouse inside the mine is more reliable,and the ability of the water supply in the mine can reach 3 000 m3/d when it has been carried out.The mine has got an obvious effect adopting this scheme of optimizing water supply object.
