    P100405NL00 1DEVICE AND METHOD FOR SIMULATING COMPOUNDDYNAMIC DISASTERS IN DEEP MINING OF COAL MINE
    BACKGROUND Technical Field The present invention relates to the technical field of simulating devices, in particular to a device and method for simulating compound dynamic disasters in deep mining of a coal mine. Related Art China is the largest coal producer and consumer in the world. Coal plays an important role in the energy structure of China. However, as a kind of non-renewable energy, coal resources are uneven in regional distribution and regional demand in China, resulting that the coal resources in China face the extremely severe situation. In order to meet the high-intensity demand for the coal resources, part of mines have to turn to deep mining, the mining depth increases year by year, and this trend is more and more obvious in recent years. In the disaster occurrence process, many factors are intertwined, which may cause each other, strengthen each other, or produce a "resonance" effect in accident breeding, occurrence and development processes, so that the occurrence mechanism of compound dynamic disasters is more complex. A simulating device in the prior art is poor in simulating effect and relatively high in cost, which does not meet the market demand, so we provide a device and method for simulating compound dynamic disasters in deep mining of a coal mine to solve the problems put forward in the above background art.

A simulating frame is slidably arranged on the supporting frame. Connecting plates are arranged between two parts of the simulating frame. A first simulating device and a second simulating device are arranged on the simulating frame respectively, and the first simulating device and the second simulating device can realize a compound dynamic disaster effect through different impact frequencies and impact intensities.

First vibration rods are arranged at an end of the guide rod and the first vibration rods penetrate through the first fixing seats. Bottoms of the first fixing seats are fixed to the simulating frame, and ends of the first vibration rods make contact with the test frame. Under driving of the motor, the convex rings rotate, when the convex rings are in a transverse state, the first vibration rods impact a surface of the test frame, then the convex rings continue rotating to be in a vertical state, and the convex rings do not make contact with the test frame. By repeating the step, a dynamic disaster high in frequency while small in impact force can be conducted continuously on the test frame.
    The second simulating device includes a second fixing seat and second vibration rods. The second vibration rods are slidably arranged on the second fixing seats. A side plate is arranged at one ends of the second vibration rods. Springs are arranged on an outer side of the side plate, and ends of the springs are connected with the second fixing seat. Under pulling of the springs, the second vibration rods move forward and transmit force to the test frame, and a dynamic disaster low in frequency while large in impact force is simulated on the test frame.
    Preferably, symmetrically-arranged slide rails are welded to the supporting frame. Sliding blocks are arranged on lower surfaces of the simulating frame. The sliding blocks are slidably clamped on the slide rails. Supporting plates are vertically welded to a lower surface of the supporting frame.
    Preferably, the convex rings are provided with annular grooves. The ends of the guide rod are movably clamped inside the annular grooves. A connecting rod is arranged between the adjacent convex rings.
