Joint Experimental Study on High Efficiency Dust Reduction Technology of Spray Foam in Roadheader
In coal mine production,dust is an important factor affecting safety,in order to reduce the dust generated by digging,the process of spraying foam inside the roadheader to reduce dust was analysed,and the feasibility of spraying foam inside the roadheader to reduce dust was verified through the working principle of the roadheader;the water jet suction device and foaming device were designed,and the important parameters of the two devices were determined through the orthogonal calculation method;the optimal parameters of the device were determined by carrying out a joint simulation experiment with a company,which verified the efficiency and efficiency of spraying foam inside the roadheader.Finally,through the joint simulation experiment with a company,the optimal parameters of the device were determined,and the feasibility and efficiency of the efficient dust reduction technology of internal spray foam in the roadheader were verified,laying a theoretical and experimental foundation for the subsequent research.
