阐述了断裂构造对煤与瓦斯突出的控制和不同构造部位瓦斯突出的差异性。因煤层围岩性质的不同,地质构造的差异,瓦斯突出的地段和危险性也不一样。主控断裂的作用形成了不同的构造应力分区,从而导致瓦斯不同程度地聚积与泄散,决定着煤与... 阐述了断裂构造对煤与瓦斯突出的控制和不同构造部位瓦斯突出的差异性。因煤层围岩性质的不同,地质构造的差异,瓦斯突出的地段和危险性也不一样。主控断裂的作用形成了不同的构造应力分区,从而导致瓦斯不同程度地聚积与泄散,决定着煤与瓦斯突出的强度、密度的分区分带性。这些研究成果对利民矿井各采区瓦斯突出危险性的预测,具有现实意义。 展开更多

Based on the investigation on shellfish resources from the intertidal zone to subtidal zone of Fenjiezhou Island,Hainan during 2012-2014,the quantity,species,ecological distribution and floristic characters of shellfish from the intertidal zone to subtidal zone of Fenjiezhou Island were analyzed.The results showed that a total of 137 shellfish species were found in Fenjiezhou Island,and they belonged to 4 classes [Polyplacophora(1 species),Gastropoda(94 species),Bivalvia(40species),Cephalopoda(2 species)],13 orders and 44 families.Among the families,Cypraeidae included 11 species,Muricacea included 9 species,Veneracea included9 species,Conidae included 8 species,Strombidae included 6 species,Cymatiidae included 6 species,and the other families all included less than 5 species.According to the characteristics of the components,most of the species belonged to the tropical or subtropical region,and they had a close relationship with coral reef.According to the floristic characters,the shellfish in Fenjiezhou Island belonged to the Indonesia-Malayan Subregion of Indo-West Pacific Region. 展开更多
