Quick-setting high-pressure micro-expansion hole sealing material for coal mine gas extraction drilling
The invention discloses a quick-setting high-pressure micro-expansion hole sealing material for coal mine gas extraction drilling, which effectively utilizes industrial wastes and low-price natural ores, reduces the cost, improves the air tightness of a grouting hole sealing material, and improves the hole sealing efficiency and safety at the same time. According to the determination, the setting time of the quick-setting high-pressure micro-expansion hole sealing material for coal mine gas extraction drilling is 25-28 min. Meanwhile, the invention discloses stirring equipment. Through the design of a sealing cover and a center gear which can be adjusted in the three-axis direction in the stirring equipment, three rotating rods in two pre-stirring barrels can be driven to rotate, the stirring frame in the mixing barrel can be driven to rotate, and the mixing barrel or the pre-stirring barrel can be stirred according to requirements by only one driving assembly.
本发明公开一种用于煤矿瓦斯抽采钻孔的速凝高强压微膨胀封孔材料，有效的利用工业废弃物、价格低廉的自然矿石，降低了成本，提高了注浆封孔材料的气密性，同时提高了封孔效率和安全性，根据测定，该用于煤矿瓦斯抽采钻孔的速凝高强压微膨胀封孔材料的凝固时间为25‑28min，同时本发明公开一种搅拌设备，通过搅拌设备内可三轴方向调节的密封盖与中心齿轮的设计，可以驱动两个预搅拌桶内的三个旋转杆旋转，也可以驱动混合桶内的搅拌架的旋转，只需要一个驱动组件，就可以根据需求对混合桶或者预搅拌桶进行搅拌处理。
