The cement-plaster bonded rock-like material is one of the most commonly used materials to simulate different rocks in physical model tests. However, the applicability of this material in solid-fluid coupling model tests is not clear because there are few research studies on the water-physical properties of this material and its similarity to the actual rock is uncertain. This paper presents a systemic experimental study on the water-physical properties of the cement-plaster bonded rock-like materials. The parameters of rock-like materials, including water absorption, softening coefficient, and permeability coefficient, were compared with those of actual rocks to analyse the applicability of such material. Then, the influence of proportion on the water-physical properties of this material was discussed. By multiple regression analysis of the test results, empirical equations between the water-physical parameters and proportions were proposed. The equations can be used to estimate the water-physical properties of cement-plaster bonded rock-like materials with specific proportion and thus to select suitable materials in the solid-fluid coupling physical model tests.

Fracture initiation is a key factor of hydraulic fracturing, as lack of research on fracture initiation position.The perforation geostress mechanical model of low permeability reservoir is built according to the rock mechanics, seepage mechanics, elastic-plastic mechanics, considering solid-fluid coupling and rock material nonlinearity. Adopting the transient analysis, low-permeability reservoir geostress distribution of different stages is obtained using the finite element, such as drilling - cementing - perforation –fracturing. Determine the fracture initiation position and fracture pressure combining with the rock failure criterion. Calculated on well Ao332-32, the error rate of initiation pressure between test and calculation is 3.5 percent. It is proved that the model is reasonable.

The water bursting disaster from the floor of mine is a complicated program involving several of subjects such as geology, coal mining, rock hydraulics and rock crack mechanics. In the paper, the two dimensional non-linear solid-fluid coupling model is used to study the difference of the water-holding capacity of the different floor combination under the condition of mining. The mini damage rock layer combination is obtained by analyzing the failure extent of floor under the mining pressure and water pressure. The water resisting capacity of the combination of b is the worst. The water resisting capacity of the combination of c is the best.
