A precise and controllable charging method of thermal expansion stone cracking agent

Abstract

The invention relates to a precise controllable agent filling method for a thermal expansion stone cracking agent, and belongs to the crossing field of new energy and the engineering technology. The precise controllable agent filling method is suitable for conducting agent filling when drilling depths are smaller than 1.5 meters. Required tools are simple. The thermal expansion stone cracking agent is filled in a loose manner without being rammed. Operation is easy. Selection and distribution of exiting drilling positions are not influenced. The precise controllable agent filling method can be suitable for use environments and conditions of existing thermal expansion stone cracking agents. The stone cracking speed and efficiency are high. The agent filling amount of the thermal expansion stone cracking agent and the placement position of an ignition head are accurately controlled in the using process. It can be ensured that the same type of rack can have the same stone cracking effect under the same drilling conduction and the same agent filling condition. By regulating and controlling the wall thickness of a filling cylinder, the short-range gathering of heat of the thermal expansion stone cracking agent is ensured. The agent filling method is scientific, the using process is safe and stable, and the normal use and construction process of the existing thermal expansion stone cracking agents is not influenced. By means of the method, the stone cracking effect can be accurately regulated, controlled and predicated, the use amount of the stone cracking agent is greatly reduced, the economical cost is reduced, and the economical effects are improved.

Description
