为解决浅埋近距离综采工作面过上覆集中煤柱矿压显现强烈的问题,以补连塔煤矿22307大采高综采工作面为研究对象,分析其过上覆集中煤柱期间的矿压显现特征及规律,结合地质条件、煤层赋存状况等相似矿井过集中煤柱的经验和科研机构的研究成果,据此提出合理分配推进与检修的时间安排、采用合理的采高、更换效验安全阀、工作面调斜、加强矿压观测等安全技术措施,有效避免22307综采工作面过上覆集中煤柱时因压力显现强烈、压力持续时间长,造成支架压死、工作面冒顶、煤巷片帮、锚杆或锚索飞溅伤人的危害,实现工作面的安全开采。
In order to solve the problem that the overburden concentration of coal pillar in overburden near shallow mining face is intense, taking the fully mechanized face of 22307 high mining height in BuLianta Coal Mine as the research object, According to the characteristics and regularity of occurrence of mine pressure, combined with experience of coal pillars collected in similar mines, such as geological conditions and occurrence of coal seams, and the research results of scientific research institutes, the reasonable arrangement of propulsion and maintenance schedule is put forward. Reasonable mining height and replacement Effective safety valve, face tilt adjustment, strengthening mine pressure observation and other safety technical measures to effectively prevent the 22307 fully mechanized mining face overlying coal pillar due to the strong pressure, pressure duration, causing the stent crushed, the face roof , Coal roadway to help, bolt or anchor splash injury hazards, to achieve safe mining face.
