Fully mechanized mining surface end airbag type air leakage rapidly blocking device

Abstract

The invention belongs to the technical field of coal mining and discloses a fully mechanized mining surface end airbag type air leakage rapidly blocking device. According to the fully mechanized mining surface end airbag type air leakage rapidly blocking device, an airbag is made of thermoplastic rubber (TPR), which is an SEBS-based (saturated styrene-butylene-styrene-based) modified material andhas high anti-ageing performance, so that the airbag can be plastic and high in elasticity and mean while achieve good thermal resistance, compressive deformation resistance and excellent mechanical performance; the inflating structure of the airbag is composed of two parts, namely a front main airbag and a side auxiliary airbag, wherein the main airbag can fill up a relatively regular large-areafree space, and the auxiliary airbag can fill up a narrow space complicated in structure to ensure the blocking effects of the fully mechanized mining surface end airbag type air leakage rapidly blocking device. The fully mechanized mining surface end airbag type air leakage rapidly blocking device solves the problem of spontaneous combustion of residual coal in goafs which is caused by air leakage and the upper end and the lower end of a fully mechanized mining surface.

Description

technical field [0001] The invention belongs to the technical field of coal seam mining, and in particular relates to an air bag-type rapid air leakage plugging device at the end of a fully mechanized caving working face. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: [0003] Coal has always accounted for more than 60% of my country's primary energy consumption structure. It is an important part of my country's energy and has an important strategic position in the national economy and social life. my country's thick and extra-thick coal seam reserves and production account for more than 40% of the total coal reserves and total production. Fully mechanized top-coal caving mining method is a kind of ultra-thick coal seam mining technology that has developed rapidly and matured in my country for more than 30 years. It has the advantages of high yield, high efficiency, and low cost per ton of coal. The major pr...
