Continuous prediction method of gas emission dynamic characteristic outburst of tunneling surface

The invention relates to the technical field of coal mine safety, in particular to a continuous prediction method of gas emission dynamic characteristic outburst of a tunneling surface, which utilizes the development state and the development trend of three factors of outburst comprehensive hypothesis of the tunneling surface of gas emission dynamic characteristic reaction of the tunneling surface and realizes the non-contact type continuous prediction technology of coal of the tunneling surface and gas outburst; and the method comprises the following steps: acquiring real-time gas emission monitoring data of an underground gas sensor from a coal mine gas monitoring system; extracting dynamic characteristics of gas emission of the tunneling surface, including average value of frequency ofthe monitoring data of the gas emission, the maximum value of the frequency per minute of the monitoring data of the gas emission and the movement minimum value of the frequency per t minutes of the gas emission; and acquiring the shape design characteristic parameters of a lane, the original desorbable gas content of a coal layer, wind rate and frequency time, sequentially acquiring characteristic index of the gas emission rate of the tunneling surface, gas desorption index and gas dividing source characteristic index, and carrying out real-time prediction and forecast of outburst risk of a working surface according to the states and the trends of the three characteristic indexes.

Tunnel orthographic image acquisition system based on laser radar LIDAR point cloud data and tunnel orthographic image acquisition method thereof

The invention discloses a tunnel orthographic image acquisition system based on laser radar LIDAR point cloud data. The tunnel laser radar point cloud data of any shape design of section contour are unfolded into a measurable laser radar tunnel orthographic image map by using a skeleton line mileage projection method and a section contour projection method, and the image map acts as a reference base map and a target quantity color numerical analysis map is superposed on the image map in a semitransparent mode. The invention also provides a corresponding method. The generated laser radar tunnel orthographic image can truly reflect the measurable image of the size and the position of the internal wall of the tunnel and can generate a tunnel orthographic image map plane user report including "4D" information to visually display the three-dimensional section deformation and flatness of each part of the internal wall of the tunnel to tunnel structure detection users. The length, the width and the area of cracks, water seepage and other tunnel defects can be actually measured so that the geometric size of the defects can be calculated. The scientific basis is provided to assessment and restoration of the tunnel defects and the production efficiency of tunnel detection is greatly enhanced.

The invention discloses a small efficient medicinal rubbish pyrolysis incinerator, which belongs to rubbish burning treatment equipment and solves the problems that a gas combustion chamber has simple structure, an auxiliary fuel is needed, the temperature cannot be accurately measured or controlled, and defects are produced in cloth bag dust removal and the like. The hearth of the incinerator consists of a pyrolysis and gasification chamber, a solid-phase burn-out chamber, a gas-phase combustion chamber and a flue gas treatment chamber; the solid-phase burn-out chamber is positioned below the pyrolysis and gasification chamber and communicated through a netlike fire grate; the gas-phase combustion chamber is arranged in parallel to the pyrolysis and gasification chamber, and the top of the gas-phase combustion chamber is communicated with a flue; the flue gas treatment chamber is arranged in parallel to the gas-phase combustion chamber and the pyrolysis and gasification chamber; and the gas-phase combustion chamber is communicated with the lower part of the flue gas treatment chamber, the gas-phase combustion chamber and the flue gas treatment chamber are provided with a fireproof baffle plate respectively, and the lower part of the gas-phase combustion chamber is provided with the netlike fire grate. The temperature in the incinerator is measured and controlled in real time through an electric heating and automatic temperature measurement and control system. A high-temperature granule dust removal and filter device avoids regeneration of dioxin, and the cost is reduced. The incinerator effectively and cleanly burns the medicinal rubbish on the aspects of incinerator shape design, ignition and combustion modes, temperature measurement and control, high-temperature flue gas treatment and the like.
