In response to the problems of low automation level, high labor intensity, and repeated support exacerbating roof damage in the passive advance support of the current fully mechanized mining face, taking the coal seam 2–2 in Shangwan Coal Mine as the engineering background, the stability of the surrounding rock is analyzed and studied using the theory of loosening circle. A mechanical model of advanced support for the fully mechanized mining face is established, and the feasibility of active advanced support for the fully mechanized mining face is studied. On site mining pressure monitoring is carried out, and the conclusions are as follows: (1) Theoretical analysis of loosening circle: The height of the top loosening circle is 1.0 m, the depth of the side loosening circle is 0.05 m, and the surrounding rock belongs to a relatively stable surrounding rock; (2) The monitoring results of bolt (cable) stress and two side support stress show that the influence range of advanced support pressure is about 35m, and the influence is significant within 15 m, with an average advanced stress concentration factor of 1.35; (3) Establish a support model for both sides of the solid coal roadway to verify the strength of active advanced support. The transportation gateway adopts special anchor cables to strengthen the support strength, which is greater than the reasonable support strength and meets the engineering requirements; (4) The on-site measurement of the bolt (cable) active advanced support shows that the displacement and loosening zone of the surrounding rock are very small, and the stability of the surrounding rock is good, which verifies the feasibility and reliability of the active advanced support.
