Multi-dimensional data measuring device for lump coal drilling process

The invention discloses a multi-dimensional data measuring device for a lump coal drilling process. The multi-dimensional data measuring device comprises an adsorption tank for adsorbing and desorbinglump coal, a reference tank which has the same size as the adsorption tank and is used for balancing pressure, and a high-low temperature test box for accommodating the adsorption tank and the reference tank, a temperature measuring drill rod is arranged in the adsorption tank, a non-contact magnetic coupling matching mode is adopted, the adsorption tank is driven by a driving motor to rotate, and the temperature measuring drill rod moves up and down through a propelling device; and the reference tank and the adsorption tank are respectively communicated with a gas source system for supplyinggas, a vacuum pumping system for pumping gas and a gas collecting device through a branch gas path and a main gas path. According to the method, various dimension data in the lump coal drilling process of the drill bit can be
