光面爆破和锚喷支护是煤炭工业中一项作用大、见效快的重大技术革新成果,应该认真推广。锚喷支护突破了旧的、传统的支护形式和支护理论,使支护由消极地承受围岩压力而变为积极控制围岩的力学形态变化,限制岩石的变形、位移和裂隙的发展,保持围岩的稳定性,使岩体自身的支承作用得以充分发挥。把围岩从荷载转化为承载,这是锚喷支护与其它支护形式的主要差别,也是锚喷支护最突出的优点。各单位在推广锚喷支护时一定要与推广光面爆破结合起来。光爆锚喷,高速高效,省工省料,工艺简单,操作方便,不仅减轻了支护工作笨 Smooth blasting and bolt-shot blasting are major technological innovations with a great effect and quick results in the coal industry and should be promoted seriously. Bolting and shotcrete support broke through the old and traditional support forms and support theories so that the support would be negatively affected by the surrounding rock pressure and become a positive control of mechanical changes in the surrounding rock to limit the deformation, displacement and fracture of the rock Develop and maintain the stability of the surrounding rock so that the supporting function of the rock itself can be brought into full play. The conversion of the surrounding rock from load to bearing is the main difference between the anchor spray support and other support forms and also the most prominent advantage of the anchor spray support. All units in the promotion of anchor spray support must be combined with the promotion of smooth blasting. Light explosion anchor spray, high-speed high-efficiency, provincial labor saving, simple process, easy operation, not only lighten the support work stupid
