rock cementation

基本解释

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.
由于软岩巷道围岩松散、强度低、胶结程度差，已严重影响矿山的正常生产。
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.
微细裂隙的良好胶结，使其端部应力集中被降低或消除，岩体屈服极限增大，强度提高。

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.
结果表明，东营凹陷下第三系深部碎屑岩地层经历了强烈的压实压溶作用和胶结作用、复杂的交代作用和多期次的溶解作用，原生孔隙消失殆尽。
