Study on the Mechanical Properties of Coal Weakenedby chemical analyses and physical properties of 12 coal

A novel method for fracturing coal is presented in this paper. A chemical solution is injected into coal under high pressure, whereby the coal is fractured and subsequently weakened by chemical erosion over time to produce an anti-impact soft structure. In this study, the mechanical properties of coal under chemical erosion were investigated, and the fracturing design parameters were optimized.Study on the Mechanical Properties of Coal Weakenedby chemical analyses and physical properties of 12 coalA novel method for fracturing coal is presented in this paper.

The typical GCVs for various coals are given in the Table 1.4.coal classification | Types & Facts | BritannicaCoal classification, any of various ways in which coal is grouped. Most classifications are based on the results of chemical analyses and physical tests, but some are more empirical in nature. Coal classifications are important because they provide valuable information to commercial users (e.g., for power generation and coke manufacturing) and to researchers studying the origin of coal.
