Intelligent coal control device and method for full-mechanized caving mining bracket of thick coal seam

Abstract

The invention provides an intelligent coal control device and method for a full-mechanized caving mining bracket of a thick coal seam, relates to the technical field of underground mining methods, andaims to solve the technical problems that a caving control system is complex in structure, is low in caving quality and the like. A caving control device comprises a caving mechanism, a coal carryingmechanism and a control mechanism, wherein the caving mechanism is arranged on the rear part of a full-mechanized caving hydraulic bracket, and comprises a hydraulic pipeline, a lifting movable column, a caving hole lifting plate and a caving amount inductor, and is used for controlling caving and monitoring the volume of outlet coal; the coal carrying mechanism is arranged below a hydraulic bracket, and comprises a scraping plate conveyor and a pressure sensor for conveying coal gangues and monitoring weight; and the control mechanism comprises a computer, an electric-hydraulic controller and a control cable for monitoring and judging caving quality and controlling caving. After coal refuse content is set by the device, monitored data of the caving amount inductor and the pressure sensorare combined to judge and regulate opening and closing of a caving hole. The device and the method provided by the invention further have the advantages of being simple in structure, flexible in operation, safe and efficient, and the like.

Description

technical field [0001] The invention relates to the technical field of underground mining methods, in particular to an intelligent coal discharge control device and method for fully mechanized caving mining in thick coal seams. Background technique [0002] In coal mining, thick coal seams (thickness ≥ 3.5m) account for a large share of production and reserves, and are the main coal seams for high-yield and efficient mining, with advantages in resource reserves. With the development of thick coal seam mining, top-coal caving mining and large mining height mining technologies have been developed rapidly and widely used. [0003] At present, the mining methods for extra-thick coal seams mainly include full-thickness fully mechanized mining with large mining height, fully mechanized top-coal caving method and layered mining method, among which fully mechanized top-coal caving method has been widely used in coal mine production . The fully mechanized top-coal caving method is ...
