Problems solved by technology

[0002] In coal mines with outburst risk coal seams, when predicting the outburst risk of the working face, it is necessary to use the cuttings index method for measurement. The cuttings index method mainly includes the measurement of cuttings per meter and the K1 value per 2 meters for prediction. When collecting cuttings, due to the limitation of the working face conditions in the downhole, if the air supply volume of the working face is too large, the cuttings will be blown away, or the cuttings will be wet due to the water spraying on the working face, etc., these results will lead to inaccurate measurement results property, for this reason, the present invention is designed to solve this problem

Embodiment

[0011] A drill cuttings collector, the main body of the drill cuttings collector is cylindrical, placed horizontally during operation, and completely closed, the upper and bottom of the cylinder run through a circular hole 1 with a diameter of 48mm-50mm, and the lower part of the drill cuttings collector placed horizontally There is a switchable coal outlet 2, which is used to export coal dust after collecting it for weighing. The end of the drill dust collector is placed horizontally facing the coal wall and a rubber pad with the same outer diameter as the bottom surface of the cylinder is processed to completely match the coal dust. Coal wall contact to prevent drill cuttings leakage.

Abstract

The invention belongs to the field of coal mine ventilation and security and relates to a device for collecting drilling cuttings when a drilling cutting index method is used for predicting outburst danger of working faces under the shaft. A body of the device is cylindrical, the device is transversally placed during working and wholly closed, a circular hole with the diameter of 48mm-50mm respectively penetrates through the upper portion and the bottom of the cylindrical device, a coal outlet which can be opened and closed is reserved on the lower portion of the device for collecting the drilling cuttings, the lower portion is transversally placed, the coal outlet is used for leading out the drilling cuttings for weighing, the drilling cuttings are collected once, a rubber gasket which is the same as the bottom surface of the cylindrical device in the outer diameter is processed at one end of the device for collecting the drilling cuttings, the end of the device is transversally placed and faces towards the coal wall, and the rubber gasket is used for completely contacting with the coal wall to prevent the drilling cuttings from leaking.

Description

technical field [0001] The invention belongs to the field of ventilation and safety in coal mines, and relates to a device for collecting drilling coal cuttings when the cuttings index method is used to predict the risk of outburst in a working face underground.
