Adopt technique scheme, square box is arranged to by described outstanding casing, forward and backward sidewall establishes piston hole, coordinate to the forward and backward side pressurization of moulded coal by increased pressure board and hydraulic cylinder, the case lid of casing is also provided with center pit, upper end is coordinated by increased pressure board and hydraulic cylinder pressurizes from the upper end of moulded coal, and the multidimensional realizing pressure loads.Make the mechanical property of the mechanical property of moulded coal and raw coal more close.Secondly, inflate under entering inflation panel by air-filled pore, groove, then arrive in casing by bleeder vent, compared with being directly inflated in casing from air-filled pore, inflation profile evenly, pressure uniform.
In technique scheme: the left side wall of described box-like body (1) is provided with gas pressure measurement hole (1e).Can pressure in monitoring box body easily.
In technique scheme: described wire guide (1d) is four, the madial wall of the box-like body (1) of the below of each wire guide (1d) has the groove (5) be communicated with wire guide (1d), the lower end of this groove (5) is communicated with groove (3).Like this, circuit is laid in groove through after groove.
In technique scheme: the length of the interior case of described box-like body (1) is 1200-1800mm, wide is 800-1200mm, and height is 800-1200mm, and the internal diameter of described aspis (1b) is 200-300mm.Box sizes is large, the detection of convenient outstanding parameter, thus can carry out the quantitative research of coal and gas prominent mechanics parameter.
Beneficial effect: the present invention is reasonable in design, structure is simple, enforcement is easy, can realize multidimensional pressurization, and inflation evenly, conveniently detects outstanding parameter.
