复杂地质条件下综采工作面浅孔爆破与动压注水相结合预先弱化技术

Under complicated geological conditions mechanized mining face Shallow hole blasting combined with the dynamic pressure water injection pre-weakening of the technology

田庄煤矿2710综采工作面在煤层富含夹矸的条件下,通过采用浅孔爆破与动压注水结合的方法,对煤层中的夹矸预先松动,有效解决了采煤机截割困难的难题,提高了我矿综采单产,同时也为相关地质条件的矿井提供了科学有效的解决方法。

This paper describes the field Mine 2710 Workface partings in coal - rich conditions, shallow hole blasting through the use of water combined with the dynamic pressure method, the coal seam partings advance loose, effective solution to the shearer cutting hard problems, improve the yield of fully mechanized coal mine 1 also related to geological conditions for the mine to provide a scientific and effective solution.
