【摘要】：利用煤礦井下采空區(qū)進(jìn)行礦井水資源儲(chǔ)存和循環(huán)利用的地下水庫技術(shù)為西部缺水礦區(qū)的綠色開采提供了新的途徑,但其推廣應(yīng)用仍需符合一定的適用條件。綜合采用現(xiàn)場(chǎng)實(shí)測(cè)與理論分析,結(jié)合神東礦區(qū)煤礦地下水庫工程實(shí)踐,開展了基于導(dǎo)水裂隙帶高度的地下水庫適應(yīng)性評(píng)價(jià)方法研究。結(jié)果表明:地下水庫儲(chǔ)水的高效循環(huán)使用是保證該技術(shù)成功應(yīng)用的關(guān)鍵,必須滿足"水源"、"庫容"和"通道"三大條件。采動(dòng)覆巖導(dǎo)水裂隙作為地下水庫水源補(bǔ)給的重要通道,是影響地下水庫適應(yīng)性的核心因素。利用"基于關(guān)鍵層位置的導(dǎo)水裂隙帶高度預(yù)計(jì)方法",判別具體開采條件導(dǎo)水裂隙帶發(fā)育高度,當(dāng)導(dǎo)水裂隙溝通區(qū)域補(bǔ)給水源(含水層)時(shí),地下水庫具備適應(yīng)性;否則,區(qū)域水源水體一般難以匯聚至井下采空區(qū),從而地下水庫中可供循環(huán)利用的水資源量將難以保證,地下水庫保水方法一般不適用。研究結(jié)果得到了神東礦區(qū)地下水庫工程的驗(yàn)證,并指導(dǎo)了李家壕煤礦地下水庫適應(yīng)性評(píng)價(jià)和地下水庫建設(shè)選址。
[Abstract]:The underground reservoir technology of storing and recycling mine water resources in the underground goaf provides a new way for green mining in the west water shortage mining area, but its popularization and application still need to meet certain applicable conditions. Based on the field measurement and theoretical analysis, combined with the engineering practice of underground reservoir in Shendong mining area, the adaptability evaluation method of underground reservoir based on the height of water diversion fracture zone is studied. The results show that the efficient recycling of underground reservoir water storage is the key to the successful application of the technology, and must meet the three conditions of "water source", "reservoir capacity" and "passage". As an important channel of water supply for underground reservoir, mining overburden water diversion fissure is the core factor that affects the adaptability of underground reservoir. By using the method of predicting the height of the water-conducting fissure zone based on the location of the critical layer, the development height of the water-conducting fissure zone under specific mining conditions is determined. When the water-conducting fissure communicates with the regional recharge source (aquifer), the underground reservoir has adaptability; otherwise, It is difficult for regional water source water to converge to underground goaf, so it is difficult to guarantee the quantity of water resources which can be recycled in underground reservoir, and the method of retaining water in underground reservoir is not suitable. The research results are verified by the underground reservoir project in Shendong mining area, and the adaptability evaluation of underground reservoir in Lijiagou coal mine and the site selection of underground reservoir construction are guided.
