The invention provides a modular drum type uncoupled blasting charge device. The modular drum type uncoupled blasting charge device comprises a guide device at the bottom. A charge cylinder is connected to the guide device. A string is fixed on the lateral side of the charge cylinder. one end of the string is connected to the guide device, and the other end of the string extends out of the chargecylinder. Explosive and a foam column are arranged in the charge cylinder. The foam column is used for filling the part without the explosive, and the cross section diameter of the foam column is thesame as the inner diameter of the charge cylinder. The charge cylinder is formed by rolling up flexible plates and fixedly connecting the flexible plates, and the outer sides of the rolled flexible plates are sleeved with a plurality of tie belts. According to the modular drum type uncoupled blasting charge device, by adopting the method of rolling the flexible plates into the charge cylinder, a detonating cord is in tight contact with the explosive cartridge, so that the generation of blind cannons is avoided. The device is low in cost and easy and convenient to operate and can be independently completed by one person, the source of materials is wide, and the labor cost is reduced.
