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。

Unconsolidated sand reservoir always be buried not deep, because of it's low cementation and high content of clay and sundry, the unconsolidated rock is easy to sanding during exploitation.
疏松砂岩气藏由于埋藏较浅、岩石胶结性差，并且粘土和杂基含量高，使得这类气藏在开采过程中容易出砂。

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.
