【正文】 ,多種不同的方案決定了礦井不同的施工設計方案。 通過畢業(yè) 設計 , 鞏固、深化和擴大所學基本理論、基本知識和基本技能。 ,由學生在畢業(yè) 設計(論文) 工作前期完成,經(jīng)指導教師簽署意見 、相關系主任 審查后生效。 培養(yǎng)了我們的創(chuàng)新能力和團隊精神,樹立良好的學術思想和工作作風。隨著科學技術的進步和煤炭生產(chǎn)發(fā)展的要求,井田開拓朝著生產(chǎn)集中化、礦井大型化、運輸連續(xù)化、系統(tǒng)簡單化方向發(fā)展,這將使煤礦的技術面貌發(fā)生根本性的變化。預應力錨桿支護體系階段是錨桿支護的新階段,其代表產(chǎn)品或結構主要有三種即桁架錨桿、水脹式錨桿和縫管式錨桿,這三類錨桿均具有良好的橫向預應力和一定縱向預應力,其支護效果已經(jīng)為國內外礦山支護實踐所證實支護理論。 【 Abstract】 In the shaft sinking process of freezing main shaft over 1 000 m deep in XinHe Coal Mine,in order to make the mine shaft safely and successfully sinking through the deep thick freezing overburden section and the high sectional freezing deep weathered base rock section and to rapidly plete the deep freezing mine shaft project over 1 000 m deep,with the improvement of the match technology of the mechanized equipment for the freezing shaft sinking,the optimization of the mine shaft inner layout,the enhancement of the mine shaft liner temperature prediction and control,the improvement of the mine shaft lining quality and rate,improvement of the freezing soil excavation capacity,the increasing of the load bearing capacity of the mine shaft freezing wall and others,the mine shaft construction technical problems of the high deep mine shaft freezing ground pressure,the slow construction speed of the large cross section mine shaft,the easy deformation failure of the mine shaft liner,the
