【Abstract】 To counter the features of gas emission in high-output and efficient fully mechanized underhand stope with caving mining, analysis was made on the constitution of gas emission sources, main gas prevention and control measures were practiced in thus fully mechanized face including reasonable air distribution, ventilation by even pressure, gas drainage from the seam being mined and gas drainage from gob. The relevant gas drainage parameters were summarized in the process of gas prevention and control and safe production in high-output and efficient fully mechanized underhand stope with caving mining was thus realized.更多还原
