The hydraulic fracturing of rock mass is one embranchment of the fissured rock mass seepage-stress coupling research.

岩体水力劈裂问题是裂隙岩体渗流-应力耦合研究的一个分支，对于它的研究目前尚处于初始阶段，许多基本的理论问题有待进一步深入研究。

The hydraulic fracturing of rock mass is one embranchment of the fissured rock mass seepage-stress coupling research. Up to now study on this problem is just in its initial stage, lots of basic theoretical problems should be researched more deeply.

岩体水力劈裂问题是裂隙岩体渗流—应力耦合研究的一个分支，对于它的研究尚处于初始阶段，许多基本的理论问题有待进一步深入研究。

According to the principle of hydraulic fracturing, a detailed analysis of forming mechanism of multiple-fractures is given.

本文从水力压裂的原理出发，采用机理剖析的方法，分析了导致多裂缝产生的主要因素。

Most of hydraulic fracturing theories are all on the basis of single fracture extension at present.

目前的水力压裂理论多数是建立在单裂缝延伸基础之上的，这种假设在大多数情况下都能满足工程实践的需要。

The later development of larger gins, powered by horses, water, or steam, multiplied productivity further.
