Abstract

The invention belongs to the field of coal mine mining, and particularly relates to a dust isolating device for coal blasting mining. The dust isolating device for coal blasting mining can effectivelyisolate a large amount of coal mine dust generated by blasting during coal blasting mining. The dust isolating device for coal blasting mining comprises a first mounting plate, wheels, a hydraulic cylinder, a drainage pipe, a second mounting plate, a mist spraying mechanism, a beam plate, a first connecting pipe, a sewage pipe, a guiding trough, a converging trough and a connecting plate. The wheels are fixedly connected to the bottom of the first mounting plate, and the hydraulic cylinder is fixedly connected to one side of the top of the first mounting plate. The drainage pipe is fixedly connected with the output end of the hydraulic cylinder. The dust isolating device has the effect that a large amount of coal mine dust generated by blasting during coal blasting mining is effectively isolated.

Description

technical field [0001] The invention belongs to the field of coal mining, in particular to a dust isolation device for blasting coal mining. Background technique [0002] At present, dust is still one of the main problems plaguing coal mine production. High-concentration dust, especially respirable dust, is the direct cause of inducing pneumoconiosis among workers. Therefore, reducing the dust concentration during coal mining is the main technical problem. [0003] In the mining of minerals, for coal seams that are not suitable for mining by machinery, blasting coal mining is generally selected. The main characteristics of blasting coal mining are: low investment, low technical requirements, and simple operation. But at the same time, the efficiency is relatively low, the resource recovery rate is low, and it is an extensive coal mining process. Moreover, due to the use of blasting technology, the working conditions of the operators are poor, and the coal mine dust raised by...
