【摘要】：為了科學合理地評價工作面頂板水疏放程度,分析了工作面涌水量預(yù)測值和疏放水觀測值等要素,構(gòu)建了頂板水疏放程度評價指標體系,劃分了相應(yīng)的評價等級標準,并利用AHP法確定了各評價指標的權(quán)重,建立了頂板水疏放程度的物元可拓模型。利用AHP-物元可拓模型對寧東煤田水文地質(zhì)條件較為復(fù)雜的5個工作面頂板水疏放程度進行了評價,評價結(jié)果均為頂板水疏放程度好,并且各工作面已經(jīng)實現(xiàn)了安全回采,實際情況與評價結(jié)果一致。AHP-物元可拓模型可以用于評價頂板水疏放程度,并且可以作為工作面采前水文地質(zhì)條件評價的參考依據(jù)。
[Abstract]:In order to evaluate the drainage degree of roof water in working face scientifically and reasonably, the factors such as the forecast value of water discharge and the observation value of water drainage are analyzed, and the evaluation index system of roof water drainage degree is constructed, and the corresponding evaluation grade standard is divided. The weight of each evaluation index is determined by AHP method, and the matter-element extension model of roof water thinning degree is established. Based on the AHP- matter-element extension model, the roof water drainage degree of 5 working faces with complicated hydrogeological conditions in Ningdong coalfield is evaluated. The results show that the roof water drainage degree is good, and the safe mining has been realized in each working face. AHP- matter-element extension model can be used to evaluate the drainage degree of roof water, and it can be used as a reference for the evaluation of hydrogeological conditions before mining.
