The invention relates to a device and method for accurately detecting the Y value of a bituminous coal gelatinous layer. The device comprises a device support, a coal cup, a motor, a lead screw and nut transmission mechanism, a pressure sensor, a probe assembly, a control system, a non-contact probe position measuring device and a locking mechanism. The probe assembly is composed of a probe and a reflecting plate, and the measuring end of the non-contact probe position measuring device acts on the reflecting plate; the locking mechanism can lock the probe assembly to enable the probe assembly to be suspended in the air or release the probe assembly to enable the probe assembly to fall freely. The free falling motion of the probe assembly is matched with the non-contact probe position measuring device, so that the position of the upper layer of the colloid is measured, the delay time (within hundreds of milliseconds) of an X-value peak point is greatly shortened, and the measurement accuracy is improved; meanw
