The invention discloses a novel coal mine sealing wall capable of being rapidly constructed and a construction technology thereof. The novel coal mine sealing wall comprises a roadway top plate, a roadway bottom plate, two roadway sides, grooves, crossed steel bars and EPS module wall bodies. The novel coal mine sealing wall capable of being rapidly constructed is constructed according to the following processes that firstly, grooves with the depth of 30 cm are dug in a roadway top plate, a roadway bottom plate and two sides of a roadway where a sealing wall body needs to be arranged; secondly, the EPS module bodies of different specifications are inserted into the reserved longitudinal reinforcing steel bars and fixed through concave-convex buckles or insertion openings, and then transverse reinforcing steel bars are placed in reinforcing steel bar clamping grooves to form crossed reinforcing steel bars; thirdly, concrete is poured into the EPS module wall body; and finally, an inner protective coating is sp
