(6) COAL is a solid, brittle, carbonaceous rock classified as anthracite, bituminous, subbituminous, or lignite by ASTM Designation D38877. Rule 1158 (Cont.) (Amended June 11, 1999)
Coal is a type of quasibrittle and elastic material. A damage variable based on texture changes can accurately reflect damage to coal. An elasticbrittle damage constitutive model of coal was defined. After comparing the simulation results to test results, such a model accurately reflects the mechanical properties of coal.
Solidgas coupling coallike materials are essential for simulating coal and gas outbursts and the longterm safety study of CO2 sequestration in coal. However, reported materials still differ substantially from natural coal in mechanical, deformation and gaseous properties; the latter two aspects are common not considered. There is a lack of a definite and quantitative preparation method of ...
Abutment — In coal mining, (1) the weight of the rocks above a narrow roadway is transferred to the solid coal along the sides, which act as abutments of the arch of strata spanning the roadway; and (2) the weight of the rocks over a longwall face is transferred to the front abutment, that is, the solid coal ahead of the face and the back abutment, that is, the settled packs behind the face.
