The constitutive law through the strain tensor contains the change of third fundamental form [Q.sub.[alpha][beta]] as shown in the tables; the thickness ratio X impacts the behavior of the shell because of the significant energy contribution due to [Q.sub.[alpha][beta]] as the ratio increases unlike the K-L classical model [3].
Huang put forward the shallow seam definition for strata control by use of three key index, the key strata, the thickness ratio of rock to soft overburden, and the depth of coal seams [7].
