Embodiment Construction

[0049] The non-explosion-proof trackless transportation method for high gas and gas outburst tunnels of the present invention is carried out through comprehensive utilization of the following steps: tunnel energy-saving ventilation step, tunnel coal seam and gas advance prediction step, gas outburst coal seam gas drainage anti-outburst treatment step, gas outburst tunnel The construction steps of uncovering the coal, the steps of predicting and controlling the amount of gas emission, the steps of gas monitoring and monitoring during tunnel construction, and the steps of locking tile cars in the gas tunnel according to the signals obtained from the steps of tunnel gas detection and monitoring. Even if the above-mentioned steps are all combined using the existing technology, the present invention can avoid the use of explosion-proof equipment, reduce the weight of the equipment, and significantly reduce both the equipment purchase cost, the use cost and the energy consumption. Th...

Abstract

The invention belongs to the technical field of tunnel construction and particularly relates to a high-gas and gas outburst tunnel trackless transportation method. The method is conducted by comprehensively utilizing the following steps of the tunnel energy-saving ventilating step, the tunnel coal bed and gas advanced forecasting step, the gas outburst coal bed and gas drainage outburst prevention treatment step, the gas outburst tunnel coal uncovering construction step, the gas gushing amount forecasting and controlling step, the tunnel construction gas monitoring and controlling step and the gas tunnel gas vehicle shutting step conducted according to a signal obtained in the tunnel gas monitoring and controlling step. According to the method, the cost invested at a time for purchasing explosion-proof equipment again is not needed, so that the cost of trackless transportation is reduced greatly, and compared with track transportation, the high-gas and gas outburst tunnel trackless transportation method has the advantages of less labor amount, less special equipment, high maneuverability, high efficiency and high yield. And all the mature technologies in the method are not only simple comprehensive application but organic combination.

Description

technical field [0001] The invention belongs to the technical field of tunnel construction, and in particular relates to a trackless transportation method for high gas and gas outburst tunnels. Background technique [0002] Trackless transport has many advantages and is widely used in tunnel construction. However, in the construction of high gas and gas outburst tunnels, the application of trackless transportation has always been limited due to the influence of safety, economic and technical factors. [0003] "Railway Tunnel Construction Specifications" (TB 10204-2002) stipulates in 14.1.5: "The construction machinery and equipment for high gas and gas outburst tunnels must use electric machinery, rail transportation and supporting construction machinery." This regulation basically prohibits the adoption of trackless transportation powered by diesel internal combustion equipment in the construction of high gas and gas outburst tunnels. [0004] The "Railway Tunnel Construc...
