【摘要】：本文基于分析開灤礦區(qū)沖擊地壓事故發(fā)生特征，在掌握開灤礦區(qū)發(fā)生沖擊地壓顯現(xiàn)規(guī)律的基礎(chǔ)上確定了開灤礦區(qū)深部發(fā)生沖擊地壓的主要因素；重點(diǎn)研究了包括埋深和側(cè)壓系數(shù)等因素對開灤礦區(qū)深部復(fù)雜地質(zhì)構(gòu)造工作面發(fā)生沖擊地壓的影響；總結(jié)了開灤礦區(qū)在沖擊地壓防治過程中所積累的一些經(jīng)驗(yàn)并參考國內(nèi)外先進(jìn)的沖擊地壓防治技術(shù)，構(gòu)建了具有信息互饋和持續(xù)優(yōu)化機(jī)制的全礦井-采區(qū)-工作面-局部的多級沖擊地壓監(jiān)測和防治系統(tǒng)；基于開灤的實(shí)際地質(zhì)構(gòu)造和實(shí)際開采情況，，提出了適用于開灤礦區(qū)深部煤層的沖擊地壓防治技術(shù)，包括開采方法的合理選擇和開采保護(hù)層等區(qū)域性技術(shù)措施，以及局部卸壓措施和強(qiáng)化巷道支護(hù)；并針對這些技術(shù)措施開展了優(yōu)化，主要包括了開采方法的優(yōu)選、卸壓巷道布設(shè)位置以及動壓巷道支護(hù)措施的優(yōu)選，進(jìn)一步削弱或消除沖擊地壓發(fā)生所需要的動力源及改善局部圍巖應(yīng)力環(huán)境。
[Abstract]:Based on the analysis of the characteristics of the impact ground pressure accident in Kailuan mining area, the main factors of the impact ground pressure in the deep part of the Kailuan mining area are determined on the basis of mastering the law of the occurrence of the impact ground pressure in the Kailuan mining area. The influence of the factors such as buried depth and lateral pressure coefficient on the impact ground pressure in the working face of complex geological structure in Kailuan mining area is mainly studied. This paper summarizes some experiences accumulated in the process of prevention and treatment of impact ground pressure in Kailuan mining area, and refers to the advanced technology of impact ground pressure prevention and control at home and abroad. Based on the actual geological structure and actual mining situation of Kailuan, a multi-stage monitoring and prevention system of impact ground pressure in whole mine, mining area, working face and local area with mutual information feed and continuous optimization mechanism is constructed. The paper puts forward the prevention and treatment technology of impact ground pressure suitable for deep coal seam in Kailuan mining area, including reasonable selection of mining methods and regional technical measures such as mining protective layer, local pressure relief measures and strengthened roadway support. In view of these technical measures, the optimization is carried out, which mainly includes the optimal selection of mining methods, the placement of pressure relief roadways and the optimal selection of supporting measures for dynamic pressure roadways. Further weaken or eliminate the power source needed for the occurrence of rock burst and improve the local surrounding rock stress environment.
