Abstract

The invention discloses an intelligent detection device and method for coal seam occurrence distribution in a regional gas control process. The equipment comprises a hydraulic drilling system, a data acquisition system and a data transmission system. The method comprises the following steps of: acquiring while-drilling information in real time by utilizing the data acquisition system, and determining drilling specific work and a distance between a drill bit and a drilling machine; judging relative positions of the drill bit entering and penetrating through a coal seam according to difference characteristics of the drilling specific work; then, changing the position of the drilling machine and a construction angle according to the requirements of a coal roadway tunneling regional gas control project, and repeating the steps to obtain multiple groups of relative position information; and finally, respectively drawing interfaces between the coal seam and a top plate and between the coal seam and a bottom plate based on a cubic spline interpolation method. According to the intelligent detection device and method disclosed by the invention, a drilling technology is combined with the regional gas control project, so that the problems of large construction amount, limited test range and the like of the drilling technology are solved.

Description

technical field [0001] The invention relates to the technical field of gas control, in particular to an intelligent detection equipment and method for the occurrence and distribution of coal seams in the process of regional gas control. Background technique [0002] Coal and gas outburst is one of the major disasters that restrict the safe and efficient recovery of deep coal resources in my country. In order to prevent and control the gas problem in the mining process, my country has always adhered to the principle of "regional measures first, supplemented by local measures" to prevent outbursts. With the continuous increase of mining depth and after the effect of regional measures reaches the standard, outburst accidents still occur from time to time, and in recent years, outburst accidents mostly occur in local geological anomalies and drainage blind areas that cannot be effectively covered by pre-drainage drilling. For example: In 2019, the "5.22" outburst accident occur...
