摘要
通过相似模型试验和极限分析的方法得出有关高压气体爆破煤压力的理论计算公式，为高压气体爆破采煤设备的设计和工业试验提供了理论依据。
According to lab model experiment and limits analysis,the theoretical calculation formula for coal breaking with compressed air was derived,which will provide important theory base for the design of airshorting mining equipment and industrial test.
