1、山東科技大學(xué)碩士學(xué)位論文潘西煤礦煤層底板突水機(jī)理及預(yù)測(cè)預(yù)報(bào)研究姓名：尹會(huì)永申請(qǐng)學(xué)位級(jí)別：碩士專(zhuān)業(yè)：礦產(chǎn)普查與勘探指導(dǎo)教師：魏久傳20050601山東科技丈學(xué)碩士學(xué)位論文摘要本文對(duì)潘西煤礦19煤底板突水機(jī)理及預(yù)測(cè)預(yù)報(bào)進(jìn)行了研究。在分析潘西煤礦地質(zhì)、水文地質(zhì)條件及以往突水資料的基礎(chǔ)上，概括出了影響煤層底板突水的六個(gè)影響因素：對(duì)采場(chǎng)煤層底板應(yīng)力狀態(tài)及項(xiàng)、底板巖層運(yùn)動(dòng)規(guī)律做了分析：綜合大采深(采深≥650m)條件下礦井底板破壞深度的理論分析、數(shù)值模擬及現(xiàn)場(chǎng)實(shí)測(cè)，以及大采深礦井實(shí)際突水資料，對(duì)大采深條件下的煤層
2、底板破壞機(jī)理進(jìn)行了探討，并提出了底板破壞深度的計(jì)算公式：分析了原始導(dǎo)高帶及采動(dòng)導(dǎo)高帶的原因和影響因素及其確定方法：分析了煤層底板的綜合阻水性能，對(duì)潘西煤礦19煤底板巖層的阻水性能進(jìn)行了評(píng)價(jià)；分析了斷裂構(gòu)造突水機(jī)制，包括斷層的原始導(dǎo)水性及采動(dòng)活化特點(diǎn)，從力學(xué)角度分析了斷層的增展機(jī)制及其對(duì)突水的影響。綜合考慮了含水層的富水性、構(gòu)造影響、水壓、隔水層阻水性能等因素，利用多源信息復(fù)合方法建立礦井底板突水預(yù)測(cè)模型，對(duì)整個(gè)礦井進(jìn)行了突水危險(xiǎn)性分區(qū)；對(duì)采場(chǎng)突水條件進(jìn)行了分析，將采場(chǎng)底板條件劃分為三種模型，并建立了相
