Experimental study of abrasive waterjet cutting coal-rock mass

Abstract
In order to accurately estimate the cutting depth and improve the cutting ability of waterjet in the deep coal-rock mass,a series of cutting tests on the sample of argillaceous limestone was carried out using the self-designed abrasive waterjet system with convergence nozzle.The protodyakonov scale of hardness of sample which originally locate on the coal seam bottom surface in a coal mine in Chongqing is 3.14.The results show that the maximum...
