1、貴州大學(xué)碩士學(xué)位論文盤江煤電（集團(tuán)）公司山腳樹礦1370運(yùn)輸石門修復(fù)方案研究姓名：王宇申請學(xué)位級別：碩士專業(yè)：礦業(yè)工程（工程）指導(dǎo)教師：劉勇鄧濟(jì)民20070501摘要摘要針對盤江煤電公司目前大部分礦井支護(hù)設(shè)計缺乏理論依據(jù)，導(dǎo)致巷道變形量大、巷道返修頻繁的現(xiàn)狀，選擇山腳樹礦1370運(yùn)輸石門作為研究對象。參考國內(nèi)外煤礦井巷支護(hù)技術(shù)，采用現(xiàn)場調(diào)研與實(shí)測、實(shí)驗(yàn)室實(shí)驗(yàn)、理論分析方法，研究分析了1370運(yùn)輸石門的軟巖類型及變形機(jī)制，得到膨脹與高應(yīng)力

2、型的復(fù)合軟巖類型，以及相應(yīng)的物化膨脹與應(yīng)力擴(kuò)容型的復(fù)合變形力學(xué)機(jī)制。通過技術(shù)與經(jīng)濟(jì)分析比較，得到錨注加錨網(wǎng)索噴的聯(lián)合修復(fù)方案，并進(jìn)行了方案的實(shí)施工藝研究，確定了合理的注漿錨桿參數(shù)和錨注施工工藝?，F(xiàn)場試驗(yàn)及觀測分析表明，錨注加錨網(wǎng)索噴修復(fù)方案有效地控制了巷道的圍巖變形，取得了顯著的技術(shù)經(jīng)濟(jì)效益。關(guān)鍵詞：軟巖類型；變形機(jī)制；技術(shù)與經(jīng)濟(jì)；錨注加錨網(wǎng)索噴；施工工藝Abstract：Aiming缸thepresentstateoflackofth
