Abstract

The invention discloses an intelligent detection equipment and method for the occurrence and distribution of coal seams in the regional gas control process. The equipment includes a hydraulic drilling system, a data acquisition system and a data transmission system. The method uses the data acquisition system to collect real-time information while drilling, and determines the specific power of drilling and the distance between the drill bit and the drilling machine; according to the difference characteristics of the specific power of drilling, the relative position of the drill bit entering and passing through the coal seam is determined; then, According to the requirements of the gas control project in the coal roadway excavation area, the location of the drilling rig and the construction angle are changed, and the above steps are repeated to obtain multiple sets of relative position information; finally, based on the cubic spline interpolation method, the interfaces between the coal seam and the roof and floor are drawn respectively. The invention combines the drilling technology with the regional gas control project, and overcomes the problems of large construction volume and limited testing range of the drilling technology.

Description

technical field [0001] The invention relates to the technical field of gas treatment, in particular to an intelligent detection device and method for coal seam occurrence distribution in the process of regional gas treatment. Background technique [0002] Coal and gas outburst is one of the major disasters restricting the safe and efficient recovery of deep coal resources in my country. In order to prevent and control gas problems in the process of mining, my country has always adhered to the principle of "regional measures first, and local measures supplemented". With the continuous increase of mining depth, after the effect of regional measures reaches the standard, outburst accidents still occur from time to time, and in recent years, outburst accidents have mostly occurred in local geological anomalous areas and drainage blind areas that are not effectively covered by pre-drainage holes. Therefore, it is particularly important to effectively detect the occurrence distri...
