The invention relates to a dry-type joint coal rock sampling device and a sampling method thereof. The dry-type joint coal rock sampling device comprises a cutting device and a sampling device, wherein the cutting device is provided with a cutting base, one end of a cutting wall is connected with the cutting base, a saw blade is mounted on the other end of the cutting wall, and a height regulating device is mounted between the cutting base and the saw blade; the cutting base further comprises a cutting track; a sliding rail base is connected with the cutting track, the sliding rail base is a two-way sliding rail and capable of moving along the cutting track or in a direction perpendicular to the cutting track, and a base translation control handwheel is mounted on the sliding rail base; a turnplate is mounted at the center of the sliding rail base and is provided with a handwheel, and rock samples are arranged on the turnplate; the sampling device comprises a sampling base, a clamping device, a diamond sampling drill bit, an openable transparent cover, a refrigerating device, an air blowing device and an exhaust fan. The dry-type joint coal rock sampling device is capable of either effectively avoiding coal briquette falling and coal rock cracking due to instability in the coal rock cutting process or accurately controlling the cutting thickness of the coal rock, and therefore, the purpose of accurate cutting is achieved.
Description
1. Technical field: [0001] The invention relates to a preparation tool for rock mechanics samples in the fields of rock mechanics engineering, petroleum engineering, mining engineering, etc., and specifically relates to a jointed coal rock dry-type rock sampling device and a sampling method thereof. 2. Background technology: [0002] Rock mechanics experiment is a key method to study the physical and mechanical properties of surface and deep underground rocks. According to the provisions of "Measurement Methods of Physical and Mechanical Properties of Coal and Rock", rock physical and mechanical tests are usually cylindrical samples, and the size is mostly Φ25mm*50mm or Φ50mm*100mm. However, most coal rocks have a complex structure, high brittleness, easy fracture, and easy compression, and there are often a large number of through or non-through, intermittent or continuous cracks inside, and their heterogeneity and anisotropy are very significant. Not only the mechanical a...
