摘要
中国煤炭资源可分为 5种变质程度共 10种煤阶 ,对其中 4种变质程度共 6种煤阶煤岩的力学参数进行了测试与研究。研究范围覆盖面广 ,所得到的力学参数有一定代表性 ,可广泛应用在煤层裂缝优化设计、地应力计算以及解决其它工程问题。
In China, coal can be divided into five metamorphism levels—ten coal steps. The mechanical parameters of four metamorphism levels—six coal steps among them are tested in rock mechanics lab of Langfang Branch of RIPED. The testing results are listed, and the obtained parameters can be widely used in hydraulic fracturing optimization design of coal bed, calculation of in situ stress and other engineering problems.
