摘要
疏降第四系底部含水層提高開采上限是煤礦安全生產(chǎn)和最大限
度的開采地下煤炭資源的有效方法之一。本文從水文地質(zhì)學(xué)、工程地
質(zhì)學(xué)、開采沉陷學(xué)、勘察工程學(xué)、采礦工程學(xué)等多學(xué)科聯(lián)合交叉的角
度，在太平煤礦鉆探、物探等各種勘探資料基礎(chǔ)上，分析上覆巖土體
的工程地質(zhì)條件，建立工程地質(zhì)模型，并以8301工作面為研究對象，
進(jìn)行工程地質(zhì)力學(xué)模型實(shí)驗(yàn)，對覆巖破壞規(guī)律和開采的安全程度進(jìn)行
了研究，綜合各種結(jié)果獲得了太平煤礦近風(fēng)化帶覆巖破壞的高度;在
水文地質(zhì)條件分析基礎(chǔ)上，參考國內(nèi)外疏降開采的成功實(shí)例，探討了
難疏放含水層的疏放技術(shù)，并推求出不同土層在覆巖破壞帶不發(fā)生潰
砂的安全水頭高度。開采實(shí)踐和實(shí)測證明了研究結(jié)果的正確可靠。
