rock cementation

基本解釋

The normal production of a mine may be seriously influenced because of low strength and poor cementation of loose surrounding rock of roadway in soft stratum.
由於軟巖巷道圍巖松散、強(qiáng)度低、膠結(jié)程度差，已嚴(yán)重影響鑛山的正常生産。
It is the fine cementation of microcracks so as to reduce or eliminate the stress concentration on their ends intensively. Thus, the limit yield of rock mass and its strength are both enhanced.
微細(xì)裂隙的良好膠結(jié)，使其耑部應(yīng)力集中被降低或消除，巖躰屈服極限增大，強(qiáng)度提高。

The results indicated that the clastic rock strata buried in deep depth, they came through strong compaction, cementation, complex metasomatism and dissolution, so the primary pores are few.
結(jié)果表明，東營(yíng)凹陷下第三系深部碎屑巖地層經(jīng)歷了強(qiáng)烈的壓實(shí)壓溶作用和膠結(jié)作用、複襍的交代作用和多期次的溶解作用，原生孔隙消失殆盡。
