【摘要】：針對我國巷道超前液壓支架支護技術(shù)存在設(shè)計標(biāo)準(zhǔn)缺失、對頂板反復(fù)支撐、運輸巷道配套復(fù)雜等技術(shù)難題,采用理論分析、數(shù)值模擬等方法對巷道超前段支護參數(shù)、架型設(shè)計、配套方式等進行分析。研究結(jié)果表明:由于巷道超前段受重復(fù)采動及錨桿、錨索支護的影響,可以采用現(xiàn)場實測與數(shù)值模擬相結(jié)合的方法確定合理的巷道超前支護距離與支護強度�；诓煌南锏罃嗝娉叽缂爸ёo要求,一般選擇四連桿式或伸縮桿式超前液壓支架,前者具有抗彎、抗扭性強的優(yōu)點,適用于大斷面巷道,而后者則具有結(jié)構(gòu)簡單、質(zhì)量輕等優(yōu)點,更適用于小斷面巷道。巷道超前液壓支架是大型巷道超前支護的主要發(fā)展方向,但仍然存在對頂板反復(fù)支撐破壞、配套空間狹窄等技術(shù)難題。
[Abstract]:Aiming at the lack of design standard for the supporting technology of leading hydraulic support in roadway in our country, the supporting parameters and frame type of the leading section of roadway are designed by the methods of theoretical analysis and numerical simulation for the technical problems such as repeated roof support and complicated supporting of transportation roadway, etc. The supporting methods are analyzed. The research results show that due to the influence of repeated mining, bolt and cable support on the leading section of roadway, the method of combining field measurement and numerical simulation can be used to determine the reasonable advance support distance and support strength of roadway. Based on different roadway section size and support requirements, four-bar or telescopic rod type lead hydraulic support is generally chosen. The former has the advantages of bending resistance and torsional resistance, which is suitable for large section roadway, while the latter has simple structure. Light weight and other advantages, more suitable for small section roadway. Advance hydraulic support is the main development direction of advance support in large roadway, but there are still some technical problems such as repeated support and destruction of roof, narrow supporting space and so on.
