Abstract
There are abundant gas and carbon dioxide resources in Xuchang coal mine. According to characteristics of gas geology, it is regarded that the lower group coal is located in the weathering zone. It includes gas, carbon di⁃oxide and nitrogen gas, and gas content and buried depth are positively correlated. The existing problems are low content of gas, carbon dioxide extraction rate, the conversion of carbon dioxide and other technical aspects. From national related preferential policies, resource advantages, coal and coal seam gas integration development technol⁃ogy, near horizontal drilling technology, coal seam fracturing technology, gas injection production technology and gas, carbon dioxide gas purification technology and other key technologies, combining with coal mining plan and other aspects of coal mine, it is concluded that there is coal and gas, carbon dioxide integrated development and u⁃tilization prospects.关键词
