摘要
为了精确测定煤矿井下瓦斯含量，利用一种新型的煤矿井下煤层密闭取心装置，对煤矿井下煤层瓦斯含量进行测定，其测定的瓦斯含量与传统方法相比提高了20％～30％。煤矿井下煤层密闭取心技术的应用为矿井设计、煤矿安全生产、瓦斯灾害治理及煤层气资源开发提供了更加准确的数据支持。
For determining mine gas content accurately, a new mine sealed coring equipment was developed. Compared to the traditional method, the accurate of gas content determined by new equipment is improved by 20% - 30%. The mine sealed coring equipment can provides more exact data support to mine design, safety production, gas disaster control and CBM resource exploitation.
