The invention provides an integrated valve group for a thin coal seam shearer. The integrated valve group comprises a main valve body. An oil path is arranged in the main valve body. A hinge body is arranged at one end of the outer portion of the main valve body. An oil inlet is located in the inlet end of the hinge body. The outlet end of the hinge body stretches into the main valve body and communicates with the oil path. A high pressure gauge is arranged on the hinge body. A brake solenoid valve communicating with the oil path is arranged at the other end of the outer portion of the main valve body. Control solenoid valve groups communicating with the oil path are further arranged at the two ends of the outer portion of the main valve body. The control solenoid valve groups are located below the hinge body and the brake solenoid valve. A low pressure gauge communicating with the oil path is arranged on the front face of the outer portion of the main valve body. A high-pressure overflow valve and a low-pressure overflow valve which communicate with the oil path are arranged on the upper portion in the main valve body. A manual-hydraulic reversing valve group communicating with the oil path is arranged on the lower portion in the main valve body. A fine filter and a one-way valve which communicate with the oil path are further arranged on the upper middle portion in the main valve body. The integrated valve group is overall arranged in two layers, and is high in integration level, reasonable in layout, small in size and suitable for the thin coal seam shearer and an ultrathin coal seam shearer.
